Introduction to the Canon Rebel T4i / 650D

Canon Rebel T4i / EOS 650D:

(After learning about the features of the new T4i here, see this other post for a comparison of the Canon Rebel T4i vs. EOS 60D)

Each year as Canon updates its high end Rebel (or xxxD) model, they borrow additional features from their more advanced (and more expensive) dSLR cameras, resulting in higher and higher quality consumer models that incorporate previous “pro” and “pro-sumer” features. The T2i then T3i added the improved 63 zone exposure metering system, 18 megapixel sensor, wireless controlled external flash, and full HD video of the pro-sumer models, plus threw in some additional menu items, custom function options, and in-camera processing features that were lacking in previous Rebels.

Trickle-Down Features: The new Canon Rebel T4i / 650D demonstrates a significant leap in this “trickle-down” trend by taking the all-cross-type 9 point autofocus system and faster continuous shooting speed from the 60D and introducing these to the Rebel line. Although these previous omissions were seemingly necessary to differentiate the Rebels from the mid-level 50D/ 60D line, they resulted in two of the few but important “shortcomings” of the Rebels: they always had a less precise autofocus system with only one cross-type AF point (the center one), and a slower frames-per-second maximum continuous shooting speed. (Learn more about why cross-type points are so great just below.) Now with these improved features, the differences between the T4i and the mid-level 60D have been significantly reduced. (The 60D still offers additional external buttons and controls, slightly more rugged build and weatherproofing, and additional Custom Function options.)

All New LCD and Movie Focus: In addition, the T4i adds a first for a Canon dSLR: a touch-screen LCD that can be used for settings selection, image review, menu navigation, and even autofocusing or shutter release in Live View. Plus it offers a totally revamped hybrid autofocus system for Live View and Movie shooting that makes use of phase detection and contrast detect, allowing for another Canon dSLR first: continuous autofocus during Live View and Movie shooting. The phase detection aspect of the new AF system allows the camera to determine both the out-of-focus distance and the direction in which to correct, finally eliminating the slow and awkward focus hunting of previous models. Add one of the new “step motor” STM lenses such as the 18-135mm kit lens or the 40mm “pancake” and the lens will now silently focus during movie shooting, thus eliminating the autofocus motor noise previously picked up by the camera’s microphone. (Did I mention the built-in mic is now a stereo mic! And there is a stereo mic input jack.) Plus the image stabilization of the 18-135mm EF-S IS STM lens is designed to counteract camera shake caused by walking while shooting video.

All Cross-Type AF Points: Cross-type autofocus points are more accurate and more desired because they can grab focus on a wider range of subjects. If your non-cross-type point is oriented only in the vertical direction, and you aim it at a subject displaying a strong line also also in the vertical direction (such as the side of a door frame) it will not be able to detect the line or a change in contrast, and will not be able to focus. Aim it at the strong horizontal line of the top of the door, and it will lock right on. (learn more about autofocus concepts here.)

So the fact that the T4i uses cross-type AF sensors for all 9 AF points means that the autofocus system is significantly more accurate, and you can confidently use not just the center AF point but all the outer points as well to focus on or track a subject. Not to mention that the center AF point is now also an even more accurate diagonal cross-type sensor when using an f/2.8 lens.

Faster Frame Rate: The T4i now boasts a more rapid 5 frames per second maximum continuous shooting speed, and incorporates the speedy Digic 5 processor, narrowing another major difference with the mid-level 60D. These features will allow you to capture quicker shots in a burst thus giving you the greater possibility of capturing just the right moment of action or the best facial expression or pose.

As mentioned, the Canon T4i also finally brings us great quality touch-sensitive (not old-fashioned pressure-sensitive) touch-screen capabilities on a Canon dSLR (with smear-resistance!). You can select and change your settings on the Quick Control Screen (Q Screen) simply by touching your choice, or use it to tell the camera where to focus during Live View shooting. It can also be used to navigate the menus, and during image playback you can easily swipe and zoom with iPhone-like multi-touch motions and response. Early reports indicate that the screen responds incredibly well, and the graphic layout of icons and options make it easy to use. This 1 million pixel LCD screen is fully articulating, as with the T3i and 60D.

New Live View/ Movie AF Modes: So in addition to the upgraded AF system during stills shooting, Canon has modified the Live View and Movie Shooting autofocus system, which now offers Face Detection+Tracking, FlexiZone-Multi, and FlexiZone-Single AF modes rather than the previous Quick, Live, and Face AF Modes. Quick Mode AF is still also available for Live View shooting. (With Quick Mode you use the 9 auto focus points, similar to the viewfinder AF Points, as displayed on the LCD Monitor. But since the camera is using the autofocus sensor to focus, it momentarily interrupts the Live View on the LCD Monitor when it flips the mirror back down to access the AF sensor.)

All of these features contribute to the T4i / 650D being quite an amazing consumer level camera. In most ways it is a higher-quality, more capable camera that the pro-sumer 50D of just a few years ago, and it will definitely fulfill the needs and expectations of most any enthusiast shooter. The only reasons one would need to step up to the 60D would be if you need more direct access to controls, buttons, and settings on the body of the camera in order to change and adjust settings on the fly, if you needed a slightly more rugged and dust/water-proof body, and wanted greater ability to customize the controls and functions of the camera with its additional Custom Functions.

Borrowing from the 5D MkIII: The specs also note that due to the faster Digic 5 processor, the T4i has Lens Aberration Correction and Chromatic Aberration Correction features as first seen on the 5D3, as well as a new Ambient Light Correction.

Note the additional Mode Dial options and Power Switch change (Movie Shooting Mode) to the Canon T4i (image courtesy of Canon USA)

Some Extras: And in addition to the standard Creative Zone shooting modes (Av, Tv, P, M) and the Basic Zone modes (Flash Off, Creative Auto, Portrait, Landscape, Close-Up, Sports, Night Portrait) the T4i eliminates the Automatic Depth of Field mode on the dial and adds Night shooting without a tripod and HDR backlight compensation. Movie Shooting mode is removed from the Shooting Mode dial and is added to the On-Off switch. The T4i includes the Auto+ Shooting Mode (Scene Intelligent Auto) introduced on the T3i and even used on the 5D Mark III, where the camera analyzes the specific scene in order to automatically determine the best and most appropriate exposure, white balance, Picture Style, focus, and other settings.

The T4i shares the same battery (the LP-E8) and the same battery grip (the BG-E8) as the T3i and T2i. The fun filter (Creative Filters) effects introduced in the previous models (including Grainy Black and White, Soft Focus, Fish-eye Effect, Toy Camera Effect, Miniature Effect) are all still available, plus a couple new ones such as Water Painting and Art Bold.

Taking Control of, and Possibly Understanding Exposure

Whenever a new photographer wishes to learn about exposure, shooting modes, and working in Manual or Aperture Priority Mode, most photographers recommend the Bryan Peterson book Understanding Exposure. It has become the go to guide because it offers explanations that no other book seems to cover as well or as thoroughly. However, many people aren’t the biggest fans of it and wish there was another guide with a slightly different approach – perhaps an easier, less confusing way to present some of the material.

Understanding Exposure has been updated for the current digital era, but it may be better to toss many of the old notions and methods that have been carried over from film, start from scratch, and approach the subject in a practical manner that applies fully to digital SLR cameras – cameras with histograms and instant feedback of the image and the exposure settings via the rear LCD screen, not to mention the ability to head straight to your computer and study and analyze your results and EXIF data.

While I contemplate writing an exposure book for the digital era, I will begin with a quick-start tutorial to exposure and metering with a dSLR:

First, don’t start with M mode yet. Start working in Av or A – aperture priority mode.

Set the camera on Av / A (aperture priority). Go into the menus and turn off Auto Lighting Optimizer and Highlight Tone Priority on a Canon and Active D-Lighting on a Nikon.

Set the ISO to an appropriate setting based on the lighting of the scene.
outdoors in sun: 100
less sun or shade: 200-400
more shade or darker: 800
indoors: 1600-3200

Set your aperture setting to whatever aperture setting you desire based on how much depth of field you want. Want a lot of depth of field with everything in focus from near to far? Set for f/16 or f/22. Want very shallow depth of field with just the subject in focus and cool background blurring? Set for f/2.8, f/4, or f/5.6.

Aim your camera at your subject, press the shutter button halfway, and see what Shutter Speed the camera selected. Is it slower than 1/125? (such as 1/80, 1/30) Then increase your ISO setting to a higher number. If you can’t or don’t want to increase ISO, use a wider aperture setting (a “lower” F number like f/4, f/5.6).

Is your shutter speed now about 1/125 or faster? (for still subjects – use perhaps 1/500 or 1/1000 for moving subjects). Take the photo.

Now, if the exposure is not coming out how you want, use exposure compensation to adjust it and then re-take the photo. Adjust it to the positive side to make the exposure lighter, and to the negative side to make the exposure darker.

Sound easy? It is! But of course, it all gets more complicated from here. For example, how did the camera determine what the proper exposure was? You can learn more about that, and how to better control the camera’s determination of exposure with Exploring Metering Modes.

And then now that you have the basics, and can move on to learning more about controling your autofocus system, locking focus and exposure – independently, how focal length and distance affect depth of field, composition, white balance, etc, etc!

You can learn all about these settings and functions in my e-book camera guides for Nikon and Canon dSLRs, such as Nikon D5100 Experience and Canon T3i Experience. Click the image below to see all the available guides and to learn more:

Don’t Let the Locations of the AF Points Dictate Your Composition

I began to discuss the autofocus modes of various dSLR cameras in previous posts including Taking Control of Your Canon Autofocus System and Taking Advantage of the Autofocus Systems of the Nikon D5100 and the Nikon D7000

In this post I wish to go into more detail about one of the reasons it is important to take control of your autofocus system, namely not allowing the locations of the AF Points in your viewfinder to dictate your final composition.

As I mentioned in previous autofocus posts, one of the essential steps in taking a successful photo is controlling where the camera focuses. If you allow the camera to auto focus by choosing its own focus point(s), it typically focuses on the closest object. This may or may not be what you want to focus on, so you should select where the camera focuses using the Auto Focus Points. For example, you often want to focus on a subject’s eyes, but if you allow the camera to choose the autofocus point itself, it may select another part of the face, or somewhere else on the body, or even a raised hand that is nearer to the camera than the face to focus most sharply on.

In addition, there are reasons to use the outer focus points and not just focusing with the center AF point and then recomposing. First, if you are taking several shots of the same subject and framing, you will not have to re-focus with the center point and recompose between each shot. And by controlling exactly where you focus, you then have greater, more precise control over the use of dramatic depth of field. Also, if you use the center point and recompose, you have swept the camera in an arc to recompose, and are thus always focusing at a distance behind the subject. This may not be as noticeable when the subject is further away, but for a close subject – especially when using shallow depth of field – the difference is critical.

One of the additional critical reasons to take control of your autofocus system is so that you don’t let the location of the AF Points dictate your composition. What happens when the subject you want to focus on is not located exactly under one of the AF Points? Even with 9 or 19 or more AF Points to choose from, they will not always be located exactly at or near where you need them to be. Recomposing or re-framing your shot is often necessary so that you can capture exactly the image you wish to and not one dictated by the locations of the AF Points as you see them in the viewfinder.

Figure 1 – The desired framing and composition of the shot I wish to take, yet no AF Point, including the selected lower right point (the larger point shown in red here) is located exactly at the woman’s head where I wish to focus. (Canon 7D viewfinder shown)

Canon 7D 5D mark II 60D T3i 600D autofocus system AF point choose select set setting
Figure 2 – Image is temporarily framed to place the selected AF Point over the woman’s head, Shutter Button is pressed half-way and held to lock focus at that distance, image is recomposed to the desired framing of previous Figure 1, and Shutter Button is fully pressed to capture the image.

Figure 1 shows the desired framing and composition of the shot I want to take, but the woman is not located under an AF Point. This composition is desired for me because it captures the entire window along with some space around it, as well as some space in front of the woman for her to “walk into” – but not an excessive amount of space. So I manually select the lower right AF Point (using Single-Point AF Mode), temporarily frame the image to place the selected AF Point over her face or head, press and hold the Shutter Button half-way to lock focus at that distance (Figure 2), and see the Focus Confirmation Light illuminate in the viewfinder. I then recompose back to the final framing I want (Figure 1) and press the Shutter Button fully to take the image. Even though the subject is moving, I do not need the sophisticated tracking of AI Servo (Canon) or Continuous Servo (Nikon) Focus Mode to keep her in focus. I can quickly lock focus using One Shot (Canon) or Single Servo (Nikon) Focus Mode, recompose, and take the image without the camera-to-subject focus distance changing significantly.

With the example images above (Figures 1, 2), focusing on the wall would not have been tragic because the distance between the subject and the background is small, and if a medium or narrow aperture such as f/8 or f/16 is used both the wall and the subject may be in acceptable focus. If the background was further away, and/ or a wide aperture such as f/2.8 was used – especially with a telephoto lens, and if the image was enlarged, you would clearly see that the camera focused on the wall and not the woman. Not to mention the fact that the wall is a somewhat consistent area of color and the AF system may have difficulty properly focusing on it. So it is best not to take shortcuts such as focusing on the wall and hoping the subject will also be in focus, because in many other situations you will not have this option. It is best to take the photo properly and to learn and practice the habit of working in the more rigorous manner if you want all your photos to be sharp.

If you would like to learn more about the autofocus systems of your Canon or Nikon dSLR camera, as well as learn to use the other features of your camera including metering modes, Aperture and Shutter priority modes, all the menus and Custom Function settings, and more, have a look at my Full Stop e-book camera guides. In addition to explaining the features and settings, the guides clearly explain when and why to use them in order to capture the images you desire.

Taking Advantage of the Nikon D5100 Autofocus System

Learn How to Use the Nikon D5100 Autofocus System

The autofocus system of the Nikon D5100 may not be quite as complicated as the 39 point AF system of the Nikon D7000, but it does offer many of the same capabilities and options, and can be a little confusing to figure out. The autofocus system includes not only the three Focus Modes used in various combinations with four Autofocus Area Modes, but also includes a few Custom Settings as well as the optional AF-L or Autofocus Lock Button.

You will first want to set up the autofocus Custom Settings so that the AF system functions how you desire.

a1: AF-C priority selection – This setting determines if attaining focus is top priority when you are in Continuous-servo AF mode (AF-C autofocus mode), or if you just want the shots to be taken even if exact focus is not attained for each shot. If exact focus is your priority, set on Focus. If getting the shots at all costs is the priority, set for Release.

a2: Built-in AF-assist illuminator – This is used to enable or disable the autofocus assist light, to assist you in autofocusing in low light. Note that the AF-assist lamp only works in AF-S mode or when the camera is in AF-A and choosing single-servo (not always under your control), and when in Auto-area AF area mode or only with the center AF point in other AF area modes.

a3: Rangefinder – This setting is used to help obtain focus when you have turned off autofocus and are using Manual Focus mode (MF) and manually focusing. (Be sure to also set the autofocus switch on your lens to M) The exposure indicator in the viewfinder is used to indicate if the subject is correctly in focus.

f2: Assign AE-L/AF-L button – This is to assign the function of the AE-L/AF-L Button., which gives you the option to use this button to lock focus or to initiate focus, and this separate those functions from the Shutter Button.

This should get you started, and I go into more detail about each of these Custom Settings, as well as all the other D5100 Custom Settings in my e-book guide Nikon D5100 Experience.

Using Autofocus
The information below is also excerpted from my e-book user’s guide Nikon D5100 Experience, so I hope you have a look at the guide in order to learn more about the AF system as well as all the other functions and controls of the D5100.

One of the essential steps in taking a successful photo is controlling where the camera focuses. If you allow the camera to autofocus by choosing its own Focus Point(s), it typically focuses on the closest object or human subject. This may or may not be what you want to focus on. So you should choose where the camera focuses using the autofocus Focus Points and selecting a specific AF point. This does not mean you have to manually focus the camera, it means you tell the camera exactly where to autofocus. But you also need to select the desired Focus Mode and Autofocus Area Mode, based on your subject and its type of movement (or lack of movement).

Focus Modes

The D5100 has three different Focus Modes to choose from, typically depending if your subject is still or moving. It also has four different Autofocus Area Modes (see below) to specify how many of the AF points are active and how they track a moving object. You can set these two functions in various combinations. First the Focus Modes.

Single-Servo AF (AF-S)
Use this mode when your subject is stationary, or still and not going to move, or if your subject is not going to move very much, or if the distance between you and the subject is not going to change between the time you lock focus, recompose, and take the shot. Lock focus on the subject and recompose if necessary. When using AF-S, you can select from two Autofocus Area Modes, either Single-Point AF where you select the AF point, or Auto-Area AF, where the camera selects the AF point(s) for you. I suggest you nearly always select your own desired AF point so that the camera focuses exactly where you want it to.

Continuous-Servo AF (AF-C)
Use this mode when your subject is moving. If the subject is moving towards you or away from you, the camera will keep evaluating the focus distance, as long as the Shutter-Release Button is kept half-pressed. You will need to use this in conjunction with the Autofocus Area Modes to determine if and how the camera tracks the subject laterally to the surrounding AF points, or if it will only track the subject if it remains at the initially selected AF point. Single-Point AF will only track the subject’s distance as it moves near or far if it remains under the selected point. It will not track lateral movement if the subject leaves the selected AF point. If the subject is going to be moving somewhat unpredictably and may leave your selected AF point before you can react, use the Dynamic-Area AF mode so that the surrounding AF points are used to maintain focus while you realign your selected AF point with the subject. If the subject is going to be moving across your field of view, set the AF-Area Mode to the 3D-Tracking mode so that the camera tracks it in any direction as it moves to the other AF points.

Focus on the moving subject with the selected AF point when using Dynamic Area Mode or 3D-Tracking Mode, or let the camera select the AF point in Auto-Area AF Mode, and then as long as the Shutter-Release Button remains half-pressed the camera will track the subject to the other focus points if it moves to them and as it moves closer or farther in distance.

Auto-Servo AF (AF-A)
This mode is a hybrid of the two other focus modes. It starts in Single-Servo AF (AF-S) mode then changes to Continuous-Servo AF (AF-C) mode if your subject starts moving. Why shouldn’t you use this all the time, then? Well, if you are focusing and then recomposing, as you may often be doing, your movement of the camera may fool it into thinking that the subject is moving and your resulting focus may not be where you want it to be, or may not be as accurate as it might be if you are using Single-Servo AF.

Manual Focus
Sometimes you may be taking several photos of the same subject from the same distance, or for some other reason want to keep the same focus distance and not have to keep re-focusing and re-composing. Or you may be taking multiple photos for a panorama. In these situations, turn off the auto-focus with the autofocus switch on the lens itself (set to M) and change your camera’s Focus Mode to MF (Manual Focus). Just remember to switch them back when you are finished. You may also wish to do this if you want to precisely manually focus with the focus ring on your lens. (Note that for lenses with “full time manual focus” you don’t need to switch to M in order to manually override when slightly tweaking the autofocus with the lens focus ring. These lenses will have M/A and M on the lens focus mode switch instead of A and M.) Use the Rangefinder feature of the D5100 to assist with manual focus – Custom Setting a3.

Autofocus Area Modes

The Autofocus Area Modes are used to set if just a single AF point is active or else how many AF points surrounding your selected AF point will be used to track a moving subject if you are using AF-C or AF-A Focus Modes.

Nikon d5100 autofocus af auto focus system lock point area mode
Selecting an AF Point using Single-Point AF and locking focus

Single-Point AF
Only one AF point will be active, and surrounding AF points will not become active to track a subject that moves away from the one selected point. This is typically used along with Single-Servo AF (AF-S) to focus on a stationary or still subject, or in a situation where you will be reframing the shot after you lock focus at a specific distance. It can also be used with accuracy with AF-S mode for moving subjects if you take the photo quickly or if you recompose and take the shot quickly after locking in focus, especially if the camera-to-subject distance does not change at all or very much in that period between locking focus and taking the photo. Use the Multi Selector to choose your active AF point as you look through the viewfinder and use the OK Button to quickly select the center AF point. If you choose Single-Point AF with Continuous-Servo AF (AF-C) or Auto-Servo AF (AF-A) for tracking moving subjects, it will only track the subject as long as it is positioned at the selected AF point, and it will not be tracked laterally to the other, surrounding points. As noted above, the single AF point you select will track a subject if it moves closer or farther away, but the AF system will not track the subject if it moves left, right, up, or down and away from your selected AF point. To do this, you use Dynamic-Area AF mode or 3D-Tracking mode.

Dynamic-Area AF
With the Dynamic-Area AF Mode, you select an AF point to tell the camera where to autofocus, and if your subject briefly moves away from that point to a neighboring point or if you lose the subject from your AF point while panning, the camera will use the surrounding AF points to help maintain focus on it. Select Dynamic-Area AF when you are photographing moving or potentially moving subjects using Continuous-Servo AF (AF-C) or Auto-Servo AF (AF-A). These modes are ideal for a subject moving closer or further from the camera but which may also move laterally away from the selected AF point faster than you can react in order to keep it located at that point, or for when you are panning and following the subject and attempting to keep it located at the selected AF point, but may have a little or a lot of difficulty doing so. Remember that you need to keep the Shutter Button half-pressed in order for the continuous focusing at the initial point or the surrounding points to occur. Note that the camera may pick up and start tracking a new subject that falls under the selected AF point if you lose your initial subject.

The Dynamic-Area AF Mode is not used to track and maintain focus on a subject that is moving across the various AF points in the frame, but rather is used to stay focused on a moving subject that you attempt to keep located at your selected AF Point. To track a subject that is moving across the frame, intentionally passing from one AF point to the next, use 3D-Tracking.

3D-Tracking
This mode is used for subjects moving across the frame in any direction, or subjects moving erratically from side-to-side in the frame, and they are tracked by areas of color. This is used when you don’t wish to necessarily pan or follow the subject to keep it located in the same part of the frame, but rather when you wish to keep the camera relatively still as the subject moves across the frame. You may select this option when you are tracking and photographing moving subjects using Continuous-Servo AF (AF-C) or Auto-Servo AF (AF-A). Again, you choose the initial AF point to locate the subject and begin the tracking. If the area of color you wish to track is too small or if it blends into the background, this mode might not be very effective.

Auto-Area AF
The camera uses all 11 AF points to detect what it thinks is the subject and automatically choose the appropriate AF point(s). Typically, the camera will select the nearest subject or a human in the frame, so it may not focus on exactly what you wish to focus on. That is why it is best to use one of the other modes and select the AF point yourself. However in certain situations such as quick sports or action scenes you may have to make use of this.

Locking Focus

The next step is to learn to lock focus independent of locking exposure, typically through the use of the AE-L/AF-L Button as noted in the f2 Custom Setting above. But for that, and numerous other important functions of the D5100, you are going to have to have a look at my e-book, Nikon D5100 Experience!

I’ve put together a video introduction to the D5100 autofocus system to compliment this article:

To learn about another important reason why you need to take control of your autofocus system, see the related post:

Don’t Let the Locations of the AF Points Dictate Your Composition

What do you do when, with your desired framing, your subject is not located exactly under or near an AF point? Even with all the AF points of an advanced Nikon D5100 or D7000, this will often be an issue. Have a look at the above post to learn why this is an issue and how to resolve it.

Grainy Black and White Challenge: XZ-1, LX5, S95, P300

I’m not usually a big fan of the “creative fun filters” that are included as in-camera processing options for many of the current dSLR and compact point-and-shoot cameras. I prefer to do my processing in Photoshop, where I can see the full quality version of the image, and have more control over the editing. However, I was playing around with the “Grainy Film” mode of the new Olympus XZ-1, and I was quite impressed with how cool, fun, and easy it is. Perhaps I should reevaluate their usefulness!

Olympus XZ-1 grainy film black and white
Olympus XZ-1 – Grainy Film

So I decided to have a look at some of the other cameras’ black and white grainy film options and see how they all compare. This is a pretty informal comparison without too much strict effort put into the “test” other than putting the subject camera in about the same place, zooming in all the way and using the maximum aperture if possible, and loosely trying to frame the images all about the same.

Since the Olympus XZ-1 inspired this experiment, I will cover that one first. The Olympus XZ-1 is a new competitor to the high end compact point-and-shoot class of cameras which includes the Canon S95 and the Panasonic Lumix DMC-LX5 – as well as the ~~upcoming~~ newly released Nikon P300. They are all roughly about the same size, and have excellent image quality and low light performance. Their features and maximum apertures vary, and there are other site, such as DPReview, that do full reviews of these models if you are more interested in learning about them.

For the Olympus XZ-1, you turn the Mode Dial to “Art.” How cool is that?! All you have to do is turn the dial and you can make art! Other cameras merely have “Scene Modes,” while the Olympus offers “Art!” In Art Mode choose Art 3, which is Grainy Film. While in Art Mode, as in most of its other modes, you can easily change the exposure compensation by pressing up on the rear dial and dialing in a (+) or (-) compensation amount, and immediately see what you will get. I kept it at 0 for this test.

The image from the Olympus, seen at the top of this post, is nice and contrasty. It has a bit of grain, but actually isn’t really very grainy. The large aperture does blur out the background nicely. Have a look at the larger version on Flickr to see it better.

Next up is the Panasonic Lumix DMC-LX5, another one of the high end point-and-shoots. For this camera you go into the My Color Mode and choose Film Grain.

Compared to the Olympus, it appears to have created more of a dark monochrome image, without the high amount of dramatic contrast. There is a bit of grain, perhaps a little more than the Olympus, but I really wouldn’t call it grainy. The background blurring isn’t nearly as dramatic as the Olympus. See larger image on Flickr.

The Canon S95 is quite a popular camera for those seeking great image quality in a compact point-and-shoot. After David Pogue wrote an ode to it in the New York Times, they really started to move off the shelves. For the S95, you use one of the Scene Modes called the Nostalgic Mode. You have a few degrees of exposure to choose from as you turn the front lens dial, which first start to affect image color, then go to sepia, and then to contrasty black and white. I choose the highest setting to get the grainy black and white look.

The contrast of the S95 image is between the other two – more than the Panasonic but less that the highly contrasty Olympus. The background really shows the grain, but is not very dramatically blurred out. Have a look at the larger version on Flickr to see it better.

Here is the entry from the Nikon P300. To get to this setting, you set the mode dial to Scene Mode, go to Special Effects, and set it for High-Contrast Monochrome.

Nikon P300 – High-Contrast Monochrome

Like the Panasonic, the contrast isn’t actually that dramatic. And I did not find any way to adjust the aperture setting while in this mode so as to take advantage of its fast lens (including the inability to change the ISO in this mode), so it used f/5.5 and thus the background blurring really isn’t very dramatic either. And this setting does not introduce any grain into the image. Have a look at a larger version of the image on Flickr.

The final camera is the Canon 60D, used here with its 18-135mm kit lens. This is a digital SLR, not a compact point-and-shoot like the others, but I knew it offers a grainy black and white option in its Creative Filters, so I added it to the mix. To use this feature, you take an image in color, then access the Creative Filters to apply the affect, and then save the new copy along with the original image. You can quickly access the Creative Filters during playback by pressing the Q Button. This one is called Grainy B/W, and is offered in three levels of contrast: Low, Standard, and Strong. I chose Standard to demonstrate the middle ground. Standard appears to be pretty contrasty, and is closer to the highly contrasty Strong setting than it is to the not-as-contrasty Low setting.

Canon 60D – Grainy B/W Creative Filter

As you can see, even on the Standard level of contrast it is quite contrasty. And you can definitely see the grain in the background of this image, which is nicely out of focus because I was able to use a long lens and a wide aperture. The Strong setting increases the contrast to a level very similar to the Olympus. See larger image on Flickr.

With the compact cameras, you can see on the rear LCD screen what you are going to get in advance, while with the Canon 60D, you can see how your original color image will be affected by the different levels of contrast.

So there you have it – the grainy black and white in-camera processing of these camera. Of the compacts, my favorite is the very dramatic look of the Olympus XZ-1, due to both its contrast and its more out-of-focus background. Thanks to my patient subject, the classic Nikon F3 with the stunning 50mm f/1.2 lens. Have a look at some real black and white grain on some of my earliest SLR photos from Rome, 1991.

Canon 7D vs. 5D Mk II vs. 50D – part II (plus 550D / Rebel T2i)

NOTE: Some of the information in this post has been updated to include the current Canon dSLR models, the 60D and the Rebel T3i / 600D. Please check out my blog post at the following link to read the most current information:

http://blog.dojoklo.com/2011/02/20/canon-t3i-600d-vs-t2i-550d-vs-60d-vs-7d-etc/

Original Post: I’ve had a lot of visits to my previous post comparing these cameras – the Canon 7D, Canon 5D Mark II, and the Canon 50D – and since that really wasn’t much of a comparison post, but rather just a link to an impartial, technically based testing site, I’ll try to give a little more insight into helping you make this decision. Please note, this is aimed towards still photographers and not videographers. I know that videographers have different priorities when making this selection, and I am not knowledgeable enough to address them. I have written some updated comparison posts which also address the Canon 60D here and here.

I’ve used the 50D and the 7D pretty extensively, so I can speak with a bit of confidence about them. I’m very familiar with the features of the 5D Mk II and how they compare to the other cameras, so I will discuss them too. I’ll address the 550D (Rebel T2i) at the end of this post. Also, all the precise specifications of these cameras can be researched online and compared, so I will discuss them on a user-experience level, but I encourage you to decide which factors are most important to you for further research. I know it is a long post with a lot to read, but if you are investing several hundred or thousands of dollars in a dSLR and lenses, you should be thorough! On a final note before I begin, you may have been convinced by forums, reviews, or online comments to question and compare image quality, auto-focus speed, ISO and noise, etc., but those factors are all nearly completely irrelevant. Each of these cameras has more than enough quality in all of those areas. Your choice should instead be based on your level and needs as a photographer, and on which camera best serves the way you work. If you wish to see this complicated choice summarized in an easy to read format, view this post (it is a bit tongue-in-cheek, but mostly accurate). And when you are done selecting a camera body, you can learn more about lenses here.

While I have your attention, I want to mention that I have written eBook tutorials for the Canon 60D and for the Canon T2i, which cover ALL the Menu settings and Custom Function settings, with recommended settings, plus in-depth descriptions of how and and why to use the cameras’ settings and features in everyday use – Your World 60D and T2i Experience.

Also, please let me know about broken links in my posts, as they seem to mysteriously happen from time to time.

Sensor Size: If you are, or plan to be a professional photographer, and you’ve limited your selection down to two or three of these cameras, you are going to want to seriously consider the 5D MkII. This is due primarily to the fact that it has a full frame sensor (a sensor approximately the size of a frame of 35mm film), which is pretty much expected for you to have as a professional. (Note that whenever I say 5D in this post, I am referring to the 5D Mark II). The 7D and the 50D have smaller sensors, with a 1.6 crop factor. This means that their sensors are a bit smaller than a frame of traditional 35mm film. A wide angle lens will not produce as wide of a field of view on a cropped sensor as on the 5D: a 16mm will give the field of view of a 16 x 1.6 = 25mm lens, but a telephoto on a cropped sensor will appear to zoom closer, thus making a 200mm lens appear to be a 200 x 1.6 = 320mm lens. You can begin down the professional path with a 50D or 7D, but you are eventually going to experience the limitations of the smaller sensors and start to understand the need for full frame. BUT…there are a few problems with this choice…

Price and Obsolescence: First, you probably haven’t run out to get a 5D MkII because of its cost. As of 5/2010, the price is $2,500. AND, the 5D MkII dates from 9/2008, and is due for an upgrade, likely in 2012, maybe as soon as later in 2011. In some respects, the 7D – being newer – has better features than the 5D, such as the advanced auto focus and metering systems and faster frame rate. Not to mention the fact that if you wait around long enough, a 7D type camera WITH a full frame sensor but a lower price than the 5D is bound to come out! But you need a camera now, so let’s continue. The 7D is $1,600 or $1,700 depending on current promotions, and the 50D is about $1,000. The 50D however, is also the closest one to being replaced (by the 60D or whatever it may be called). This doesn’t mean that it isn’t still a very capable and feasible camera – people are still happily using 20D and 30D cameras, just that it is reaching the end of its production life. So as far as the newest model, that is the 7D (and the 550d/ T2i).

Megapixels / Image Quality: Regarding megapixels, it really isn’t much of an issue unless you plan on printing out billboard size prints. All of these cameras have more than enough megapixels and image quality for most photographers’ needs. The 7D is at 18mp, the 5D Mk II at 21mp, and the 50D at 15mp. I have found that more megapixels give you more lee-way to push and pull the image around in Photoshop before it starts to fall apart and look over manipulated. In this respect there is a significant difference between 8 megapixels of a Rebel XT and 15 or 18 mp. The 8mp barely allow you to do a regular amount of exposure, contrast, and color correction before it starts to really show, but there is little to be concerned about between the 15mp of the 50D and 18mp of the 7D (unless you are a hard-core pixel peeper, in which case you will be deeply offended by these kinds of statements). Be aware that sensors with more megapixels more readily show the shortcomings of cheaper lenses, and thus demand higher quality lenses, like the Canon L series, for the sharpest, most detailed image across the entire frame. From experience, I can tell you there is a huge improvement in clarity, color, and overall image quality when using an L lens with a 50D or 7D.

HD Video: If you are concerned about HD video, then you choice is narrowed down to the 7D and the 5D Mk II. With firmware updates and 3rd party Magic Lantern firmware, they are about on par as far as frame rates etc., so cost and sensor size is again the differing factor here. If you are not going to need or use video, it is definitely worth considering the 50D, which will give you 85-90% of the still photography features and performance of the 7D at a much lower price.

ISO, Frame Rate, File Size: For ISO performance, you can look at the testing site mentioned above to see that they are incredibly similar. Being a professional camera, the 5D has a broader ISO range on both ends, lower noise at higher ISOs, and a better dynamic/ tonal range. This is a large factor in why you pay $2400 for this camera. But for the non-pro, in general you hardly ever want to go above ISO 1,600, so unless you have a specific reason for needing really high ISO and photos with the lowest possible noise at high ISOs (for example shooting lots of indoor or dark events like concerts, weddings and receptions), then this isn’t much of a deciding factor. And if you are concerned about dynamic range, well, don’t be. Anyone who actually needs to be concerned about dynamic range is a commercial photographer who is not reading this post because they are busy choosing between a $7,000 camera and a $10,000 camera. The frame rate performance, however, may be an important factor depending on how you work and what you take photos of. The 7D has a continuous rate of 3fps and a high speed continuous rate of 8fps. Personally, I’m unhappy with this choice of rates. The 3fps is too slow for action situation, and the 8fps is ridiculously high, giving me far too many unwanted photos that quickly fill up the memory card. I wish for a rate closer to 5 or 6 fps. The 5D has one rate of 3.9fps, which again seems a bit too slow for action situations, and limits its use for capturing sports action. The 50D offers 3fps and 6.3fps, which I find ideal. Oh, also, the file size of the 7D images are much larger than the files of the 50D and somewhat larger than the files of the 5D. While this indicates that the files contain more information and detail, this affects size and number of memory cards you will need, plus size and expense of storage on your hard drive and external hard drives, PLUS the time it takes to download, transfer, copy, open, save, and upload files. It is a significant hidden cost in storage dollars and time of the 7D that should not be ignored. (Is this apparent difference of the 7D and 50D images visible to the naked eye of anyone other than pixel peepers and people making jumbo prints? Not necessarily. The image quality you need is available from any of these cameras, so it is more productive as a photographer to focus on image content!)

Features, Customization: Being the newest camera, the 7D has the most advanced features. As I mentioned above, it has an advanced auto focus system, providing more focus points, more focus modes (single point, spot, zone, expansion, etc.) and numerous options for how the focus points perform and select and track a subject. I’ve written a bit more about these features here, along with links to additional resources. There are advanced custom functions for auto focusing and tracking, flash control (the 7D is the only one which offers remote flash capabilities, which will save you a couple hundred dollars on Pocket Wizards if you are going to use this), and customization of buttons and displays. Again, I’ve explained a lot of these features in this post. Read through them. Do you understand them? Are you going to learn them? Are you going to need and use them? Probably not. They are nice to have, make you feel like you have a really powerful camera you are in control of if you learn how to choose, set and use them, but in everyday shooting I rarely, if ever, make use of them. The live view (which the 50D has as well) and the built in level are cool, but will you ever use them? I don’t. (The built in level will be most useful to landscape photographers). Of all the features and customizations of the 7D that are not on the older 50D, the only ones I miss are the remote flash capability, the grid overlay in the viewfinder, the larger more inclusive viewfinder, the spring loaded doors of the 7D, and the ability to switch functions of the top dial and back dial in Manual mode. (It is such a nice feature on the 7D – since I use Av mode most of the time, the top dial controls aperture. But when I switch to M mode, the top dial now controls shutter speed. So with the 50D I have to overcome muscle memory and use the back dial for aperture. But with the 7D, one can switch the dials’ functions.) Unless you are an intense sports or animal shooter who needs to customize how the camera selects and auto focuses on a moving object, how it addresses an object that moves in front of your subject, and how fast it responds to this new object before it addresses or ignores it, then you don’t need these features. And when you compare the features of the 7D to the 5D or 50D, you find that the older cameras are not outdated dinosaurs as forums will lead you to believe – but rather they also have many of these features and customizations as well. As far as all the new auto focus features of the 7D, it turns out they barely mattered to me because I manually select my auto focus point 99% of the time. I don’t want the camera necessarily focusing on the closest object, and it certainly does not know what I wish to focus on, so I don’t leave it up to chance, and I select the point myself. Therefore I rarely use any of these advanced auto-focus modes. In addition, it is much easier and quicker to manually select an auto focus point on the 5D and the 50D when you are selecting from 9 focus points rather than the 19 focus points of the 7D! However, if you photograph fast moving objects that you would prefer the camera to locate, track, and properly focus on, most of the time, all by itself, then the 7D is the camera for you. Also, note that due to the fact that the 5D is a professional body and not a consumer level camera, it does not have a built in pop-up flash. If you plan to use a flash with it, you will need to buy the Canon 580EX II flash (which you should do with any of these camera anyway).

It is expected that the 5D Mk III and possibly the 60D (or whatever it may be called) will also incorporate this new 7D type focusing system when they come out. The 5D, 7D, and 50D all have AF microadjustment capability, which means that you can adjust the auto-focusing of each lens individually, in the camera, if they happen to front- or back-focus a little bit. The problem is that it is a maddening procedure, and you can never get it quite right because the focusing typically varies slightly for each focus point, as well as for different distances and apertures. (You may get it exactly sharp for the center focus point at 15 feet at f/4, yet find that it is still off for the upper left focus point when you shoot under real life conditions that vary from those settings.) I feel that if you need an excessive amount of AF microadjustment, you should probably send the camera or lens back for repair, calibration, or replacement. Personally, if I were using a non-L-series lens, I wouldn’t worry about a few mm of front- or back-focusing. And if I were using an L-series lens that didn’t focus dead on, I would send it back to Canon for recalibration – which in fact is something I have done. (I don’t understand people’s celebration of AF microadjustment – isn’t it a built in admission of poor manufacturing quality control, especially when pairing a Canon lens with a Canon body?) Finally, be aware that the mode dials of the 7D and 5D do not have most of the “basic zone” mode settings such as sports, portrait, and landscape. As the user of such an advanced camera, you are expected to know how to change the camera’s settings (aperture, shutter speed, ISO, etc.) yourself for these types of situations. If you don’t, and/ or if you plan on keeping your camera set on Auto (so called “green box mode”) or Program (P) mode, you probably shouldn’t be considering a 5D, 7D or 50D anyway, because you’ll be paying for far more camera than you will be using! Start with the 550D or one of the other Rebels for now and upgrade later if you feel you have outgrown its capabilities. If you are concerned about the best image quality, your image quality difference between a 7D on Auto and a 550D on Auto will be negligible. (Note that these cameras also have a Creative Auto mode, which is a weird “transitional” mode between Auto and actually learning how to make use of aperture settings and exposure compensation in Av, Tv or M mode. Since using aperture settings to dictate desired depth of field is essential to photographic composition, it is best you actually learn it directly.)

Metering: The 7D has an advanced metering system compared to the 5D Mk II and the 50D, and this is actually one very important advantage. The 7D has a more precise 63 zone metering system vs. the 35 zone system of the 5D and 50D. With the 7D, I can confidently leave it on evaluative metering 97% of the time, and it meters the subject exceptionally well 98% of those times. Canon claims that it will meter properly for a wide variety of subjects, including back lit and extreme contrast subjects. I have found this to be true. Compared to the 50D, this is significant. I have found that the 50D regularly overexposes by about 1/3 or 1/2 a stop, and I have exposure compensation on -1/3 all the time to avoid blown out highlights (except in dark situations, where it tends to under-expose). Also, the 50D just does not always correctly expose in unusual or difficult lighting situations. And for dramatic and powerful photos, you want unusual or difficult lighting situations, so I have found that I am using exposure compensation, or having to change to center weighted, partial, or spot metering often. While this is sharpening my metering eye and skills, it is a pain and it leads to the risk of lost shots. I would prefer that it just got the exposure right the majority of the time, as the 7D does. (I have subsequently found that using center-weighted averaging mode on the 50D all the time results in more consistent exposures than evaluative metering mode). You can learn more about the various metering modes, and when to use them, in this post.

550D / Rebel T2i: The Canon 550D or Rebel T2i has some impressive specs, and shares many features of the 50D and the 7D, and it is actually the newest model of all of them. It has 18mp and HD video like the 7D, but only 3.7fps continuous shooting mode frame rate. And it has 9 AF points and less complex auto focus options, like the 50D. It is fully capable of taking photos that are virtually the same quality as the 7D and the 50D, and if you don’t have intensive shooting and ego demands (ie, wanting the biggest, most expensive body whether or not you actually understand, need, or use its advanced features), it is worth seriously considering. But the 550D can’t have every feature and custom function of the higher level cameras, otherwise it would just be a 7D! If you are concerned about comparing image quality, ISO performance, auto-focusing speed, etc, all of these cameras have more than enough of what you need. You should instead be comparing the features and advanced options of the cameras which are most important to how you work. The top of the line camera won’t help you take better photos. But mastery of the tool that best fits your need just might (when combined with good knowledge of composition and lighting). I encourage you look at Flickr users’ photos taken with an “old,” 8MP Rebel XT to confirm this. Also, don’t rule out the Canon Rebel XSi if you are just starting out with digital SLRs.

If you are comparing a 5D Mk II vs. 550D (5D vs. T2i) you are looking at a professional full frame camera vs. a consumer, entry level dSLR, and skipping 2 pro-sumer cameras in between. So while the features of the 550D are nearly on par with the 7D in many ways, the 550D vs. 5D MkII is an odd comparison that quite frankly confuses me. Are you new to digital SLRs? Get a 550D (or a 50D/ 60D if you wish to spend more money or need the higher frame rate for sports or photojournalism). Have you outgrown all the features, capabilities, or limitations after extensive use of a 20D, 40D or 50D? Get a 5D MkII. (Note that whenever I say 5D, I am referring to the 5D Mark II, the current model at this time). Are the images you’ve been taking with your Rebel or 40D no longer living up to your professional level needs in terms of dynamic range and noise at high ISOs? Get a 5D. Want to spend $2,400 on a camera body? Get a 5D. Want to spend $800 and still have a tool that is fully capable of taking professional quality images? Get the 550D.

There are a few reasons why you would need a 7D or a 50D over a 550D / T2i. A major one is the advanced controls over camera settings. The more expensive models have additional buttons, controls, and displays on the exterior of the camera to enable quicker changes of important settings and easier viewing of what the current settings are. The 550D is capable of changing all these settings too, it is just done in a different way. For example, the 7D and 50D have the big dial on the back for quickly scrolling through menus, images, and for quick exposure compensation changes and changes of other settings. They also have the little toggle joystick on the back, primarily for quickly changing focus points. These 2 cameras also have the additional display screen and buttons on the top to easily view and change a number of settings such as ISO, drive mode, white balance, and metering mode – among others. These cameras are designed for a professional or advanced user who makes use of all these settings and needs to quickly change them while working. However, with a little practice, these settings can also be quickly changed using the buttons and big screen on the back of the 550D. The 7D and 50D also have advanced menus which give the user more customization options, like those discussed above (27 custom functions on the 7D vs. 12 on the 550D), and additional features desired by advanced users or pros, such as 1/3 ISO increments where the 550D has full increments (100-200-400 etc.).

What you are also paying for with the 7D and the 50D are stronger, better constructed metal bodies to handle daily use and abuse as well as some weatherproofing of the buttons and doors. (However, Canon cameras have fallen from elephants and airplanes and have survived, so they are all generally pretty rugged. At pitcher of water was thrown on the back of my Rebel XT and it was fine.) All these features give the 7D and 50D a bigger and heavier body than the smaller, lighter 550D, which may be an important consideration for some users. Also, the 7D, and 50D have AF microadjustment capability, but the 550D does not. AF Microadjustment means that you can adjust the auto-focusing for each lens, in the camera menu, if they happen to front- or back-focus a little bit. I don’t think this is a very important feature, as I discuss above in Features. (The problem is that it is a maddening procedure, and you may get the focus exactly sharp for the center focus point at 15 feet at f/4, yet find that it is still off for the upper left focus point when you shoot under real life conditions that vary from those settings.) As I said above, if you need an excessive amount of AF microadjustment, you should probably send the camera or lens back for repair, calibration, or replacement. Or if you are that obsessed about pixels, you should be looking at a pro-sumer or pro camera and L series lenses. Finally, the 550D also uses SD type memory cards, while the other cameras all use CF, and the smaller battery of the 550D will not last for as many shots as the other cameras.

Also, as I discussed above, be aware that the mode dials of the 7D and 5D MkII do not have most of the “basic zone” mode settings such as sports, portrait, and landscape. If you are starting to learn dSLR photography, these modes are helpful for seeing the results from different camera settings, and are good shortcuts until you have learned more about apertures and shutter speeds. Or if you never intend to use or learn more about the advance settings, the basic modes are good for helping you get better looking results than Auto or Program modes. So if you plan on keeping your camera set on Auto, Program, or the basic modes (sports, landscape, etc.), start with the 550D or one of the other Rebels for now and upgrade later if you feel you have outgrown its capabilities. Your image quality difference between a 7D on Auto and a 550D on Auto will be negligible.

So there you have it. You can read great, in depth reviews of each of these cameras on DPreview.com. There are probably numerous features and points that I forgot to mention, but hopefully this will give you a starting point in determining which features are important to you, and what warrants further research to help you in making your decision. The important thing is to choose one that fits your needs and budget, then stop comparing and get out and shoot! As I said above, your camera choice should be based on your level and needs as a photographer, and on which camera best serves the way you work. Whichever one you choose, I highly encourage you to get the the applicable Canon Guide to Digital SLR Photography from David Busch, or a similar book like the Magic Lantern Guides. They are much more user friendly versions of the camera’s manual, and will get you up and running quickly and assist you in fully understanding the settings, controls, and functions of your dSLR.

Depth of Field Simplified

I’ve noticed that a lot of searches regarding depth of field (and how to use your aperture to create a blurred or blurry background in your photos, or what is called bokeh) have led to my blog. I’ve also received some good follow up questions from my previous post about depth of field. Unfortunately, my post on Mastering Depth of Field may be a bit advanced for those who are still learning about how to use their digital SLR, as it is intended for more experienced photographers.

As I explained in that post:

“depth of field is…the range of distances in which the objects in the photograph will be acceptably sharp. For example, if I am using a 100mm lens, set my aperture at f/5.6, and focus on a subject 10 feet away, everything from 9.69′ to 10.3′ away from me will be acceptably sharp or in focus in the resulting image.”

Depth of field, then, can mean that everything is in focus from a few feet away to infinity (deep depth of field), or it can mean that a person’s eyes and nose are in focus, but their ears and hair and everything behind (and in front) of them is blurry (shallow depth of field). One of the best ways to make use of depth of field is to create dramatic, shallow depth of field – the subject is in focus, but the background is blurry. This technique helps to call attention to your intended subject and minimize distracting background elements, and to make your photos look much, much more like those of the pros.

All of the numbers and fractions and settings and seemingly reverse logic are intimidating at first, and most books add to the complication and confusion. But it is really quite simple. Depth of field is controlled by the aperture. A small aperture size (which is an aperture number like f/16 or f/22) will create deep depth of field, with everything in focus. A large aperture size (which is an aperture number like f/2.8 or f/4) will create a shallow, dramatic depth of field. (Since “f/number” is a fraction, f/16 is a smaller number and size than f/4, so I’m avoiding using small number vs. large number terminology, as I said I would try to keep this from becoming too confusing…) So here is the quick and simple way to create dramatic depth of field:

Set your camera on Aperture Priority Mode. On a Canon, rotate the mode dial to Av, on Nikon set the dial to A.

Set your camera to Auto ISO. Or else if you wish to control the ISO, if you are indoors or in dim light without a flash, set it to 800 or 1600 ISO. If you are outside in bright sun, set it to 100 or 200 ISO. If it is a bit cloudy or you are in the shade set it to 200 or 400 ISO.

Look in you manual for how to change the aperture setting of the lens. For a Canon dSLR in Av mode, that means rotate the little finger dial up there by the shutter button. On a Nikon it means rotate one of the dials at the top right front or back of the camera, depending on your camera and settings.) Turn the dial until you see f/2.8 or f/4 or f/5.6 on your screen or in the viewfinder. Since you are in Aperture Priority Mode, the camera automatically selects an appropriate shutter speed. If you’ve selected the ISO yourself, or even if you are using Auto ISO, you may want to verify that an appropriate shutter speed is being selected. For example, I found that with the Canon 7D, Auto ISO often selects a much slower shutter speed than what is best for a situation. Press the shutter button half way down and check the shutter speed. If it is anywhere from 1/100 to 1/250 or higher, you are fine if your subject isn’t moving. If the subject is moving, make sure the shutter speed is 1/250 to 1/1000. If it is any higher or lower than the range you want, you should adjust the ISO until the shutter speed it falls into that range (raise the ISO, keep the aperture the same, and this should result in the camera selecting a faster shutter speed setting).

Focus on your subject using the focus mode of your choice, and take the photo. Preferably, use single point focus mode and select the focus point you want, so that you have complete control over where the camera focuses. If the subject is a person or animal, focus on the eyes or eyebrows. If it is something else, focus on what you want to be sharpest in the photo.

A good book to read to continue learning about this is Understanding Exposure by Bryan Peterson (Third Edition). Click on the link to see it on Amazon. It is geared towards photographers just learning about apertures, shutter speeds, and ISO, and helps to explain the concepts better than most other guides.

Let me know how the photos come out! Note in the first photo above that dramatic depth of field can be used to make the foreground blurry as well, not just the background.
