Now that you’ve decided on the Canon Rebel T5i / EOS 700D (or Canon Rebel T4i / EOS 650DCanon Rebel T3i / EOS 600D) you’ll want to get the basic, essential accessories. Don’t get carried away yet with elaborate flash modifiers and color balance correction tools before you gain some experience and determine which advanced accessories you will really need and use. But you can’t go wrong with these initial 10 additions to your camera bag. Click on the links or the images to view and purchase them on Amazon.com or from the manufacturer (and help support my blog by doing so – thanks!)

1. SanDisk Extreme 8GB or 16GB Memory Card – You are going to need a high quality, high speed memory card to save all those images and capture those videos. Go with the best and don’t risk corruption and errors – a SanDisk Extreme. Perhaps a couple 8GB, 16GB, or even 32GB capacity Secure Digital (SD) cards to capture and store your photos – more if traveling. Use at least class 6 cards, or better yet class 10 if you will be shooting video.  Be sure to check the Sandisk site for current rebates.

2. Canon LP-E8 Battery – You will probably want a spare battery, especially if you are traveling, or just for those times you forgot to charge the battery before going to an important event. Go with the official Canon brand and avoid battery communication and charging issues. If you are a fan of the optional battery back / vertical grip, the one for the T3i and T4i is the Canon BG-E8. The battery grip allows you to use 2 LP-E8 batteries for extended shooting, or six AA batteries, and also increases the size of the camera body, which some users find more ergonomically comfortable, especially when shooting in the portrait orientation.

3. Canon T5i/700D Experience e-book (or Canon T4i Experience E Book or Canon T3i Experience E Book) – You will want to go beyond Auto and learn to use the advanced functions and settings of your sophisticated camera, so be sure to check out my e books, Canon T5i/700D Experience, Canon T4i Experience and Canon T3i Experience. They will help you to take control of your camera so that you can consistently take better images – the images you wish to capture. You’ve invested the money in an advanced camera, now invest the time to learn how to use it to its full potential! (There is also a Canon T2i Experience book available.)

4. Black Rapid RS7 Strap – This sling-style camera strap provides a more comfortable and practical – and somewhat more discreet – way to carry around your camera, especially if you have a larger lens on it. They also make a couple of slightly different versions of the sling-strap, such as one designed for women, and a active “sport” version.

5. Manfrotto 055XPROB Tripod Legs and Manfrotto 496RC2 Ball Head:  This is an excellent “starter” combination of tripod legs and head for the enthusiast.  They are sturdy and durable yet affordable.  If you know you will be doing a lot of tripod work, such as for studio, landscape, or travel photography, it is best to invest in more advanced (expensive) versions, including lighter carbon fiber legs, four section legs that close to a shorter length, and a head with additional or specialized features.

    

6. Giottos Large Rocket Blower – Blow the dust off your lens, camera body, interior, and sensor safely with the Rocket Blower. Get the large size for maximum “whoosh!” Use with the LensPEN Lens Cleaning System to clean those fingerprints, smudges, and mysterious spots off your camera lens (filter) safely and quickly with the LensPEN. Brush off the loose spots with the brush end, “charge” the tip with a twist of the cap, then clean by “drawing” in a circular motion. Read the manufacturer’s instruction for complete details.

 

7. Canon 430EX II Speedlite Flash – Upgrade to the Canon Speedlite Flash to obtain more flash power and control for your low light pictures. Take advantage of the T3i’s wireless remote flash capabilities. Rotate and bounce your flash for more flattering indirect light, diffuse it and scatter it for less harsh shadows. Consider the Canon 580EX II Speedlite for more advanced needs.

7a. Stofen Omni Bounce Diffuser – Diffuse and scatter the light from your Speedlite flash with the Omni Bounce Diffuser to eliminate harsh shadows. Use it with your flash head at a 45 degree angle up, or to the side or behind you, as it is designed to be used. Don’t aim it straight on, and don’t use it outside. I don’t care if you see others doing that, even if they have a 5D and a big lens – they don’t know that all they are doing is wasting flash power and not affecting the results.

8. B+W Brand UV Filter – Protect your lens from scratches, dust, and impact damage with a high-quality, multi-coated B+W brand UV filter. It generally shouldn’t affect your image quality due to its high quality glass and coatings, and it just may save you from a $200 repair. Leave one on each of your lenses at all times, unless you are using another filter like the circular polarizer. Be sure to get the right size filter for your lens.

8a. B+W Brand Circular Polarizer Filter – Use this high-quality, multi-coated filter to dramatically darken skies, increase contrast, and cut through reflections. Turn the rotating lens to adjust the amount of darkening or reflection.

9. Canon EF-S 18-200mm f/3.5-5.6 IS Lens – After you’ve realized the limitations of the kit lens in both quality and focal range, pair your T3i with this high quality all-purpose “walk-around” lens, great for everyday and travel use. It provides the full focal range from wide angle to telephoto, and delivers excellent image quality, color, and contrast, as well as Image Stabilization to prevent blur from camera movement.

9a. EW 78D Lens Hood – And you will want the lens hood for the 18-200mm lens, to shade the lens from unwanted glare and flare and protect it from bumps and bangs.

10. M Rock Holster Bag – Carry and protect your camera and walk-around lens in a holster style bag from M Rock. I used the Yellowstone style extensively in my travels throughout South America, and I love its durability and extra little features like a built-in rain cover, micro-fiber cleaning cloth, zippered interior pocket, adjustable interior, and extra strap. Be sure to get the model that fits your camera body and lens-length.

Bonus. Understanding Exposure by Bryan Peterson – If you don’t yet understand the relationship between aperture, shutter speed, and ISO, read this book immediately. This knowledge is essential to understanding and using your powerful dSLR to its full potential.

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.

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.

This article mostly applies to the 9 point autofocus system of the Canon 60D and the Rebels including the T5i / 700D and T4i / EOS 650D (and their predecessors), as well as to the new Canon 6D and its 11 AF points.  The Canon EOS 7D also shares the same Autofocus Modes discussed below, but it adds Autofocus Area Modes to the mix as well as additional Custom Functions affecting the AF system, so I will have to address those additional capabilities in the future (or you can learn all about them now in my Canon 7D Experience e-book).  I have written a separate post that addresses the AF system of the Canon 5D Mark III.

You can learn much more about using these cameras with my Full Stop e-book camera guides for Canon dSLR cameras.

Using Auto Focus
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.  This does not mean you have to manually focus the camera, it means you tell the camera exactly where to autofocus.  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.  If you are capturing an image of a bird in a tree, the camera has no idea you want the autofocus system to zero-in on the bird so that it is in sharp focus and not the branches or leaves near it, or the leaves closest to you.

Autofocus works by looking for contrast, so try to focus (place your AF Point) on a detail with a strong line or strong contrast between light and dark.  It may not be able to focus on a large area of consistent color – such as a white wall or blue sky or even an evenly colored and lit shirt – or on a subject that is too dark.  It can be disrupted by regular patterns or confused when looking through close objects to objects farther away, such as looking through a fence.  And it sometimes fails to work as well in dim light, though the AF-Assist Beam can assist in this situation.  When photographing people, always try to focus somewhere on the face, ideally on the eyes or eyebrows, then recompose the framing of your image if necessary.

Select an Auto Focus Point, or AF Point, using the Multi-Controller or using the AF Point Selection Button and the Cross Keys (depending on your camera).  If you have a model with the Multi-Controller (such as the 60D with the thumb-pad or the 7D or 5DII with the thumb-joystick), be sure to set the Custom Function setting for AF Point Selection Method so that you can directly change the AF Point without pressing the AF Button first.

Figure 1 – The selected AF Point is located over the subject’s eye in order to ensure the camera autofocuses where desired.  (Canon 60D viewfinder shown, T3i/600D viewfinder similar)

To see how autofocus point selection works, make sure the switch on your lens it set to AF and your Autofocus Mode, as seen on the top LCD Panel or rear LCD screen, is set to One Shot, then:

•    Tap the Shutter Button with a half-press to wake up the camera.
•    Looking through the viewfinder, use the Multi-Controller or Cross Keys to select the focus point that is nearest to where you want to focus.
•    Place that point over your intended subject.
•    Press and hold the Shutter Button halfway down and see that point blink red.  The Focus Confirmation Light should light up in your viewfinder.  You have locked the focus.
•    Keeping the Shutter Button pressed halfway, recompose if necessary, and take the shot by fully pressing the Shutter Button.

There are reasons to use the outer focus points and not just the center one all the time.  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 (think of an arc that is your focus distance, and the tangent line off that arc that is the focus plane which now runs behind the subject after re-composing).  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.

It may sound difficult to select the focus point each time, but it is actually very quickly done and should become instinctive.  You may even start to set your focus point as you approach a scene before even bringing your camera to your eye.

Focus Modes
The 60D and T3i (and 5D/ 5DII and 7D) have different focus modes to choose from, typically depending if your subject is still or moving, or if you wish to track its movement.

One-Shot AF
Use this mode when your subject is 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.  This mode can even be used for moving people or objects if you quickly take the shot after establishing or locking focus.

Focus on your subject by pressing the Shutter Button halfway.  The active or selected AF Point will be displayed or will illuminate, and the Focus Confirmation Light at the lower right in the Viewfinder will illuminate as well.  Continue to press the Shutter Button all the way to take the shot.  If you half-press the Shutter Button to lock focus on your subject, the camera will remain focused at that distance as long as you keep half-pressing the Shutter Button.  You can recompose the shot as you wish and then full press the Shutter Button to take the photo.

As just noted, if the Focus Confirmation Light does not light up and the camera does not take the photo, the camera may not be finding enough contrast to focus on, you may be too close to your subject for the lens to focus, or the lighting may be too dim for the AF system to work properly.

However, if you are photographing a subject that is approaching or receding from view at a relatively constant rate, or photographing fast or erratic or unpredictably moving subjects, or photographing sports, action, or wildlife you will usually want to use AI Servo Focus Mode.

Figure 2 – Use One-Shot AF mode and select your desired AF Point to capture still or moderately moving subjects.  (Canon T3i viewfinder shown – 60D similar)

AI Servo
AI Servo mode is used for tracking and focusing on moving subjects, and is ideal for capturing sports and wildlife including birds.  If the subject is moving towards you or away from you the camera will keep evaluating the focus distance as long as the subject remains under the focus point that was originally active and the Shutter Button is kept half-pressed, and if the subject is moving from side to side or throughout the frame the camera will track it as it passes from one AF Point or Zone to the other ones (if you started tracking with the center AF point on the 60D and T3i or any selected AF point with the 7D).

If the subject is going to be moving across your field of view, set the camera to automatically select the focus point using all the AF points (this is one of the few times you will not be manually selecting the auto focus point), focus on the moving subject with the center focus point, and then as long as the Shutter Button remains half-pressed the camera will track the subject to the other focus points if it moves to them.  Thus when the image is taken, the subject is in focus.  This will even work in conjunction with continuous shooting.  If you keep the Shutter Button fully pressed and continue to take photos, the camera will keep focusing on the moving subject.  As you can imagine, this is ideal for tracking a player running across a field, a dog running toward you, or a bird moving across the fame.  Note that when shooting with Continuous Shooting Drive Mode not every shot may be in sharp focus as the camera sometimes can’t keep up and accurately predict the subject’s speed or location.  But you should be able to capture many sharp images with this technique.  The more sophisticated Canon 7D will allow you to start tracking moving subjects with any selected AF Point and not just the center AF Point.  These are the types of advanced capabilities you are paying for (and should take advantage of!) with a more expensive dSLR.

As you will see, when using AI Servo mode your compositions will be partially dictated by the positions of the autofocus points in your Viewfinder.  The subject needs to be at one of these AF Points in order for the camera to maintain focus on it.  This is why in some situations becoming skilled at quickly using One-Shot AF – even for action scenes – will give you much more ability to control your compositions.

AI Focus
This mode is a hybrid of the two other focus modes.  It starts in One-Shot AF mode then changes to AI Servo mode if your subject starts moving.  Why shouldn’t you use this all the time, then?  Well, it is typically not the best of both worlds.  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 then activate subject tracking AI Servo Mode, and your resulting focus may not be where you intend it to be or may not be as accurate as it could have been with One-Shot AF.  And in AI Focus Mode it may not be as quick to respond to a moving subject as it would in AI Servo Mode.  Typically you know if your subject is still or moving so it is better to select one of the other two AF Modes.  Plus that way you always know which AF Mode you are working in and can either lock focus where you want it or begin tracking a subject without wondering what mode the camera is in and if it will suddenly change.  But there may be situations that call for this combination mode such as a still bird or animal that may start moving unexpectedly, so keep it in mind.

How do you remember which mode is which since the terms “AI Servo” and “AI Focus” tell you nothing that makes sense?  Although I listed them in a different order above to explain them more easily, on your camera they are listed:

ONE SHOT
AI FOCUS
AI SERVO

Remember that One-Shot AF just focuses once and doesn’t change once you lock it in, and AI Servo AF is the other extreme – continuous focus used for moving objects. And AI Focus AF is listed in the middle, between the two, because it is the hybrid, combination of the two.

Checking Focus
You can review your images on the rear LCD Monitor of your camera to try to determine if they are in focus, especially by zooming in as close as possible.  But be aware that this screen has only about one million dots or pixels, while your actual image has about 18 million pixels.  That means that many images will appear to be in proper focus on your LCD screen, but you might discover that the actual images are not really so sharply in focus.

Before continuing, I want to mention that much of this text is excerpted from my dSLR guides for the Canon EOS 6D, Canon 70D, Rebel T5i / EOS 700D, Rebel T4i / EOS 650D, and the Canon EOS 7D. If you would like to learn more about the autofocus systems as well as all the other features of your camera including metering modes, Aperture and Shutter priority modes (Av and Tv), 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.

To learn about another important reason why you need to take control of your autofocus system, and why the two example photos above actually weren’t my final compositions, see the next 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 the 19 or 39 points of an advanced Canon 7D or Nikon D7000, this will often be an issue.  For example in Figure 2 above, I actually wish to capture the entire window and more space around it within the image frame, but moving the camera and framing for that composition leaves me with no AF Point at the woman where I wish to focus.  Have a look at the above post to learn why this is an issue and how to resolve it.

Focus and Depth of Field

Many functions of dSLR cameras are related to some degree or another, and Focus and Depth of Field are two of these.  The depth of field, based on your aperture setting (and thus related to exposure…) expands forward and back from your point of focus.  Thus, one important aspect of controlling your depth of field begins with focusing exactly where you want to.  To begin learning more about depth of field, have a look at my post Depth of Field Simplified.

It is one thing to know that your cool new Canon or Nikon digital SLR provides you with 3 or 4 different metering modes. It’s another thing to know how and when to actually use them in the field or in different real life situations. The Canon 5D, 7D, 60D, 50D and T3i all offer four different metering modes – Evaluative, Center-Weighted, Partial, and Spot – as I’m sure you have thoroughly read about in your manual, right? Nikons, like the D7000, D51000, and D3100 generally have three different modes: Matrix, Center-Weighted, and Spot. I’ll try to cut to the chase and simplify the explanations and their uses.  Note that there are some important differences between how they work for Canon and Nikon cameras, particularly the Spot mode.

Evaluative (Canon) or Matrix (Nikon): This is the default mode for your camera, and it can be used for almost every situation you shoot. Yes, maybe 90% of the time, maybe more. The camera evaluates the entire scene, as divided into several zones, and chooses the best exposure based on its knowledge of thousands of potential image situations. The current metering systems are so good, they can even be relied on for backlit or other challenging lighting situations. An important feature of this mode is that advanced cameras such as the Canon 7D, Canon 60D or Nikon D7000, D5100 take into account the selected focus point in its determination of exposure settings. It is assuming your focus point is on your most important subject, so under challenging and critical situations, it is wise to confirm that the camera has chosen the focus point you want (well, this is always wise). Even better, you should typically manually choose the focus point or cluster of focus points, as the camera has no idea what your intended image is. So in special situations, such as dramatically back-lit scenes or a situation with bright light plus deep shadows, make sure you are not using the center point to focus and meter, and then recomposing to take the shot – because some of the zones that the camera evaluated are now no longer in your shot after recomposing, and other new areas are, so the camera has set exposure for an image other than the one you are taking.

Partial (Canon only): This mode meters a smaller area, about 9.4%, in the center of the scene on the 7D and 6.5% with the 60D. Nikons do not have this mode, though some Nikons such as the D7000 offer the ability to change the size of the Center-Weighted Metering circle (see Center-Weighted Metering below), so it makes up for this.  The area is approximately a circle that reaches to the top and bottom focus points, and the metering system ignores the rest of the frame. This mode is useful where there is a dramatic difference in lighting between the foreground or subject and the background. For example, when your subject is backlit – maybe standing in front of a bright window or the sun – and consequently their face is in shadow. I know I said evaluative mode can often handle this type of situation, but if you want the face or subject to be properly exposed and not risk blowing the shot, it is worth it to quickly switch to Partial metering mode. Again, another time to use this is when there is a wide range of light in your scene, from bright sunlight to deep shadows. Remember, this mode is not linked to your focus point. The partial area that is metered is always in the center, so meter on the part of the scene that is most critical and that you want properly exposed, using the central area of the viewfinder, lock in that exposure, then recompose and take the shot.

Important Note about Locking In the Metered Exposure: The metered exposure setting is sometimes locked in by pressing the shutter button half-way down or sometimes not “locked” until the image is taken (depending on your camera, or current shooting mode, or how you set it up – read your manual!).  The shutter button also typically locks focus (unless you have changed that setting).  If you wish to lock in focus and exposure separately, which you often will need to do, on a Canon use the AF-Lock (for focus) button and/ or the AE-Lock (for exposure) button – which looks like this: * – to lock in one of them before locking in the other with the half-press or full press of the shutter button. On the Nikons, you have to set one of your buttons to be the exposure lock button, either the AE-L/AF-L Button or the Fn Button on some cameras like the D7000. I suggest first metering on the subject and locking in that exposure by pressing the appropriate button, then recomposing and locking in focus right before or as you take the photo. Or else learning the advanced methods of back button focusing. Get in the habit of knowing how to do this instinctively, and if you need to hold or just press the particular button, so that it comes naturally during critical situations. On the 7D and D7000 and other cameras you can also customize how these buttons perform or set other buttons to do these tasks. You can see in the viewfinder that you have locked focus when the focus dot is lit. You can see that exposure is locked with the AE-L indication in the Nikon viewfinder or the * symbol in the Canon viewfinder.

Locking exposure and focus, independently, each in the brief seconds before you take a shot? Confusing? A little, but not impossible to figure out with some experimentation and practice. Remember, this is why you bought the fancy dSLR, so that you could make use of all these advanced features and take your photos to another level!

Center-Weighted Average: This metering mode is sort of a cross between Evaluative and Partial metering. It acknowledges that the subject is in the center and requires special metering attention, but it also takes into account all the other zones. Again, this is not linked to the focus point, but always to the center, so if your subject is off center – which it typically should be for a more dynamic image – you need to lock in exposure on your subject and then recompose. I have found that with the Canon 50D, this mode is actually more consistent than Evaluative metering, which often over exposes by 1/3 or 1/2 a stop.  Note that you can use the Custom Settings of the D7000 to change the size of the center area being weighted.

This mode can be used when you want to ensure that the subject is properly exposed, but you also want the camera to consider the background. However, if the background is much darker or lighter than the subject, and you want the camera to expose only for the subject and ignore the background, use Spot Metering…

Spot: This mode meters a small center area, 2.3% of the frame with the 7D, 2.8% with the 60D, and 2.5% with the D5100 and D7000. This area is indicated by the small circle in the center of the viewfinder of the 7D and 60D. There is no center circle in the Nikon viewfinder and you will soon find out why.  So when do you want to use Spot metering? This, again, is useful for scenes with great variation in light and shadow, or in very critical situations. One of the most common ways to use it is when metering for proper exposure on a dramatically lit face or subject, but the exposure of the rest of the scene is unimportant. Or perhaps your subject is set against a plain but consistent background, like a bird against a large blue sky. It is also used to determine proper exposure of a subject before switching the camera to manual for a controlled studio shot, or a critical shot or series of shots where the lighting is not going to change. If your background is completely dark or extremely bright, and you don’t want the exposure system to consider it at all when determining the exposure of you subject, use Spot rather than Center-Weighted or Partial. With Canon cameras, the Spot that is used to evaluate the exposure is in the center of the frame, and is often indicated by a small circle. However, with Nikon cameras like the D5100 and D7000, the Spot surrounds the active focus point and is not necessarily in the center of the frame unless you are using the center AF point. So it is wise to become familiar with how your camera operates.

A fifth metering mode is Manual metering, which isn’t actually a mode in your camera, but is a method of metering. This is where you use a light meter or use your camera as a light meter (such as described at the end in the Spot section above) and then manually set your exposure based on the meter readings. This is used when you want ultimate control of the metering and exposure.

I recently ran across an interesting article which takes this discussion to another level by addressing the use of different metering modes in the very specific situation of a wedding. Since one of the main subjects in typically all in white, and the other in black, the metering mode you select and where you meter can make a dramatic difference in the exposure. While that article is specific to weddings, it is useful and helpful to read to further understand how the different modes work, and how special situations might call for some extra thought.
