Introduction

Canon has done it again It's packaged up many of the most alluring features of two of its advanced digital SLRs (in this case, the Canon EOS 50D and EOS 7D) and stuffed them into a compact, highly affordable body called the EOS Rebel T2i (in the USA and some other countries EOS 550D elsewhere except in Japan, where it is the Canon EOS Kiss Digital X4). Your new camera is loaded with capabilities that few would have expected to find in an entry-level dSLR. It has 18 megapixels of resolution,...

Ingredients of Canons Alphanumeric Soup

The actual product names of individual Canon lenses are fairly easy to decipher they'll include either the EF or EF-S designation, the focal length or focal length range of the lens, its maximum aperture, and some other information. Additional data may be engraved or painted on the barrel or ring surrounding the front element of the lens, as shown in Figure 6.5. Here's a decoding of what the individual designations mean EF EF-S. If the lens is marked EF, it can safely be used on any Canon EOS...

Your First Lens

The Canon EOS Rebel T2i is frequently purchased with a lens, often the Canon EF-S 18-55mm f 3.5-5.6 IS autofocus lens, which adds only about 100 to the price tag of the body alone, and is thus an irresistible bargain. You can sometimes buy the T2i body alone if you already have some lenses and find a dealer that doesn't stock only kits. Other Canon models, including the EOS 1D Mark III, EOS 1Ds Mark III, and EOS 5D Mark II, are generally purchased without a lens by veteran Canon photographers...

Nonbracketing Is Exposure Compensation

When the three bracket indicators aren't separated, using the left right cross keys simply, in effect, adds or subtracts exposure compensation. You'll be shooting a bracketed set of one picture, with the zero point placed at the portion of the scale you indicated. Until you rotate the Main Dial to separate the three bracket indicators by at least one indicator, this screen just supplies EV adjustment. Also keep in mind that the increments shown will be either 1 3 stop or 1 2 stop, depending on...

Shooting Movies

The Canon EOS Rebel T2i can shoot full HDTV movies with monaural sound (or stereo sound if you plug in an external microphone) at 1920 X 1080 resolution. In some ways, the camera's movie mode is closely related to the T2i's Live View still mode. In fact, the T2i uses Live View type imaging to show you the video clip on the LCD as it is captured. Many of the functions and setting options are the same, so the information in the previous sections will serve you well as you branch out into shooting...

Ok

White balance bracketing will occur in two stop steps along the blue amber (yellow) axis. The amount of the bracketing is shown in the lower box to the right of the graph. This form of bracketing is similar to exposure bracketing, but with the added dimension of hue instead of brightness darkness. Bias bracketing can be performed in any JPEG-only mode. You can't use RAW or RAW+JPEG, because the RAW files already contain the information needed to fine-tune the white balance and white balance...

Digital Photo Professional

Digital Photo Professional, introduced earlier in this chapter, is preferred by many for Canon dSLR cameras like the Rebel T2i. DPP offers much higher speed processing of RAW images than was available with the late, not lamented, sluggardly File Viewer Utility (as much as six times faster). Canon says this utility rivals third-party standalone and plug-in RAW converters in speed and features. It supports both Canon's original CRW format and the newer CR2 RAW format used by the T2i, along with...

Image Stabilization

Canon has a burgeoning line of more than a dozen lenses with built-in image stabilization (IS) capabilities. This feature uses lens elements that are shifted internally in response to the motion of the lens during hand-held photography, countering the shak-iness the camera and photographer produce and which telephoto lenses magnify. However, IS is not limited to long lenses the feature works like a champ at the 17mm zoom position of Canon's EF-S 17-85mm f 4-5.6 IS USM and EF-S 17-55 f 2.8 IS...

Connecting Multiple Units to Your Canon EOS Rebel Ti

Non-dedicated electronic flash units can't use the automated E-TTL II features of your Rebel T2i you'll need to calculate exposure manually, through test shots evaluated on your camera's LCD, or by using an electronic flash meter. Moreover, you don't have to connect them to the accessory shoe on top of the camera. Instead, you can use an adapter in the hot shoe to provide a PC X connector, and use a shutter speed of 1 60th second or slower. You should be aware that older electronic flash units...

Getting into Focus

Learning to use the Canon EOS Rebel T2i's autofocus system is easy, but you do need to fully understand how the system works to get the most benefit from it. Once you're comfortable with autofocus, you'll know when it's appropriate to use the manual focus option, too. The important thing to remember is that focus isn't absolute. For example, some things that look in sharp focus at a given viewing size and distance might not be in focus at a larger size and or closer distance. In addition, the...

Introducing Live View

Live View is one of those features that experienced SLR users (especially those dating from the film era) sometimes think they don't need until they try it. It's also one of those features (like truly silent shooting, without any shutter click) that point-and-shoot refugees are surprised that digital SLRs (until recently) have lacked. As I noted earlier, SLRs have actual, mechanical shutters that can't be completely silenced, as can be done with point-and-shoot cameras. I've fielded almost as...

You'll find that the Shooting menu options are those that you...

Lens Hoods

Lens hoods are an important accessory for all lenses, but they're especially valuable with telephotos. As I mentioned earlier, lens hoods do a good job of preserving image contrast by keeping bright light sources outside the field of view from striking the lens and, potentially, bouncing around inside that long tube to generate flare that, when coupled with atmospheric haze, can rob your image of detail and snap. In addition, lens hoods serve as valuable protection for that large, vulnerable,...

Canon Eos Rebel T2i Internal Memory

However, reduced image quality can sometimes be beneficial if you're shooting sequences of photos rapidly, as the T2i is able to hold more of them in its internal memory buffer before transferring to the memory card. Using the RAW+L or RAW settings, the largest burst you can expect will be 3 to 6 shots. Eschew RAW and go for JPEG Fine at maximum resolution, and you might get more than 34 photos in a single burst. Canon says that with a JPEG Medium setting, bursts of up to 1120 shots are...

Managing Lots Of Files

The only long-term drawback to shooting everything in RAW+JPEG is that it's easy to fill up your computer's hard drive if you are a prolific photographer. Here's what I do. My most recent photos are stored on my working hard drive in a numbered folder, say T2i-01, with subfolders named after the shooting session, such as 100601Trees, for pictures of trees taken on June 1, 2010. An automatic utility copies new and modified photos to a different hard drive for temporary backup four times daily....

Clean now To Clean manuaily

You can activate automatic sensor cleaning immediately or enable disable the feature. Some say that CMOS sensors, like the one found in the Rebel T2i, attract less dust than CCD sensors found in cameras from other vendors. But even the cleanest-working photographers using Canon cameras are far from immune. Fortunately, one of the Rebel T2i's most useful features is the automatic sensor cleaning system that reduces or eliminates the need to clean your camera's sensor manually. As I mentioned in...

Telephoto Extenders

Telephoto extenders (often called teleconverters outside the Canon world) multiply the actual focal length of your lens, giving you a longer telephoto for much less than the price of a lens with that actual focal length. These extenders fit between the lens and your camera and contain optical elements that magnify the image produced by the lens. Available in 1.4X and 2.0X configurations from Canon, an extender transforms, say, a 200mm lens into a 280mm or 400mm optic, respectively. Given the...

Advanced Shooting and Movie Shooting with Your Canon EOS Rebel TiD

Getting the right exposure is one of the foundations of a great photograph, but a lot more goes into a compelling shot than good tonal values. A sharp image, proper white balance, good color, and other factors all can help elevate your image from good to exceptional. So, now that you've got a good understanding of exposure tucked away, you'll want to learn how to work with some additional exposure options, use the automatic and manual focusing controls available with the Canon EOS Rebel T2i,...

More On Viewing With A Television

Canon makes it quite easy to view your images on a standard television screen, and not much more difficult on a high definition television (HDTV), as I noted earlier in this chapter. (You have to buy a separate cable for HDTV.) For regular TV, just open the right port cover on the left side of the camera, plug in the cable supplied with the camera into the socket labeled A V OUT Digital, and connect the other end to the yellow VIDEO RCA composite jack on your television or monitor. For HDTV...

Setting Up Your Canon EOS Rebel TD

Canon has made the migration path through its Rebel (formerly Digital Rebel) digital camera line so seductively easy that it's a safe bet that many of you are jumping to this latest entry-level model directly from an earlier EOS camera, like the Rebel XSi, or even the relatively new T1i. The enhanced features of the Canon EOS Rebel T2i 550D are hard to resist, including a whopping 18 megapixels of resolution and honest HDTV movie-making capabilities. So, if you do have experience with a...

Enabling Live View

You need to take some steps before using Live View. This workflow prevents you from accidentally using Live View when you don't mean to, thus potentially losing a shot, and it also helps ensure that you've made all the settings necessary to successfully use the feature efficiently. Here are the steps to follow. 1. Choose a shooting mode. Select a Creative Zone or Basic Zone shooting mode. Unlike the previous model Rebel T1i, Live View now works with any of the Basic Zone modes in the T2i. You...

Your Autofocus Mode Options

Choosing the right autofocus mode and the way in which focus points are selected is your key to success. Using the wrong mode for a particular type of photography can lead to a series of pictures that are all sharply focused on the wrong subject. When I first started shooting sports with an autofocus SLR (back in the film camera days), I covered one game alternating between shots of base runners and outfielders with pictures of a promising young pitcher, all from a position next to the...

What Lenses Can You

The previous section helped you sort out what lens you need to buy with your T2i (assuming you already didn't own any Canon lenses). Now, you're probably wondering what lenses can be added to your growing collection (trust me, it will grow). You need to know which lenses are suitable and, most importantly, which lenses are fully compatible with your Rebel T2i. With the Canon T2i, the compatibility issue is a simple one It accepts any lens with the EF or EF-S designation, with full availability...

EyeFi Upload

As I mentioned in Chapter 3, the Eye-Fi settings appear in the Set-up 1 menu only when you have an Eye-Fi memory card installed in your camera. A company called Eye-Fi (www.eye.fi) markets a clever SD card with wireless capabilities built-in. They currently offer four models, including the basic Eye-Fi Home (about 50), which can be used to transmit your photos from the T2i to a computer on your home network (or any other network you set up somewhere, say, at a family reunion). Eye-Fi Share and...

Making Sense of Sensors

The number and type of autofocus sensors can affect how well the system operates. As I mentioned, the Canon EOS Rebel T2i has nine AF points. The original Digital Rebel and Digital Rebel XT had seven autofocus points, and Canon's high-end cameras, like the 21MP Canon EOS-1Ds Mark III has a whopping 45 autofocus points. These focus sensors can consist of vertical or horizontal lines of pixels, cross-shapes, and often a mixture of these types within a single camera, although, as I mentioned, the...

Adjusting White Balance

I showed you how to adjust white balance in Chapter 3, using the T2i's built-in presets, white balance shift capabilities, and white balance bracketing there's more on bracketing in Chapter 4, too . In most cases, however, the Rebel T2i will do a good job of calculating white balance for you, so Auto can be used as your choice most of the time. Use the preset values or set a custom white balance that matches the current shooting conditions when you need to. The only really problematic light...

You can select one of the Basic Zone modes suitable for your subject matter Portrait, Landscape, Close-up, Sports, or Night Portrait and the camera will do an excellent job of calculating the right settings to give you an outstanding picture with...

Bibble

One of my personal favorites among third-party RAW converters is Bibble Pro, which just came out with a new version as I was writing this book. It supports one of the broadest ranges of RAW file formats available which can be handy if you find yourself with the need to convert a file from a friend or colleague's non-Canon camera , including NEF files from Nikon D1, D1x h, D2H, D100 CRW files from the Canon C30 D60 10D 300D CR2 files from the Canon EOS Rebel T2i and other newer models ORF files...

Flash Firing

Use this option to enable or disable the built-in or accessory electronic flash in Creative Zone modes. When disabled, the flash cannot fire even if you accidentally elevate it, or have an accessory flash attached and turned on when using the Creative Zone modes. There are several situations in which you might prefer to totally disable the T2i's built-in and accessory flash. Flash might be a no-no when shooting in sensitive environments, such as concerts, in museums, or during religious...

You can change which of the nine focus points the Canon EOS Rebel T2i uses to calculate correct focus, or allow the camera to select the point for you. As I mentioned in Chapter 1, in A-DEP, or any of the Basic Zone shooting modes, the focus point is always selected automatically by the camera. In the other Creative Zone modes, you can allow the camera to select the focus point automatically, or you can specify which focus point should be used.

Here are a few ideas to get you started Take revealing images. Fast shutter speeds can help you reveal the real subject behind the fa ade, by freezing constant motion to capture an enlightening moment in time....

Tiny Slice of Time

Exposures that seem impossibly brief can reveal a world we didn't know existed. In the 1930s, Dr. Harold Edgerton, a professor of electrical engineering at MIT, pioneered high-speed photography using a repeating electronic flash unit he patented called the stroboscope. As the inventor of the electronic flash, he popularized its use to freeze objects in motion, and you've probably seen his photographs of bullets piercing balloons and drops of milk forming a coronet-shaped splash.

Many of the problems that telephoto lenses pose are really just challenges and not that difficult to overcome. Here is a list of the seven most common picture maladies and suggested solutions. Symptom flat faces in portraits. Head-and-shoulders portraits of humans tend to be more flattering when a focal length of 50mm to 85mm is used. Longer focal lengths compress the distance between features like noses and ears, making the face look wider and flat. A wide-angle might make noses look huge and...

White balance shift allows you to dial in a white balance color bias along the blue amber yellow dimensions, and or magenta green scale. In other words, you can set your color balance so that it is a...

Sorting The Motor Drives

Incorporating the autofocus motor inside the lens was an innovative move by Canon, and this allowed the company to produce better and more sophisticated lenses as technology became available to upgrade the focusing system. As a result, you'll find four different types of motors in Canon-designed lenses, each with cost and practical considerations. AFD Arc-form drive and Micromotor MM drives are built around tiny versions of electromagnetic motors, which generally use gear trains to produce the...

Biasing Your White Balance

White balance bracketing is confusing enough, until you start adding some bias to the equation. Fortunately, the concept is easy to understand with a little explanation. As I noted above, white balance bracketing usually proceeds along a single axis, either the blue amber horizontal or green magenta vertical axis . If you stick to those directions, the bracketing dot indicators will confine themselves to the thicker center lines that bisect the grid shown in Figure 3.19. You can move the...

The first setting is the Review time option described earlier under the Shooting 1 menu. That big three-inch LCD uses a...

Avoiding Dust

Of course, the easiest way to protect your sensor from dust is to prevent it from settling on the sensor in the first place. Some Canon lenses come with rubberized seals around the lens mounts that help keep dust from infiltrating, but you'll find that dust will still find a way to get inside. Here are my stock tips for eliminating the problem before it begins. Clean environment. Avoid working in dusty areas if you can do so. Hah Serious photographers will take this one with a grain of salt,...

Guide Numbers

Guide numbers, usually abbreviated GN, are a way of specifying the power of an electronic flash in a way that can be used to determine the right f stop to use at a particular shooting distance and ISO setting. In fact, before automatic flash units became prevalent, the GN was actually used to do just that. A GN is usually given as a pair of numbers for both feet and meters that represent the range at ISO 100. For example, the Rebel T2i's built-in flash has a GN of 13 43 meters feet at ISO 100....

Making Light Work for

50000 Shutter Speed

Successful photographers and artists have an intimate understanding of the importance of light in shaping an image. Rembrandt was a master of using light to create moods and reveal the character of his subjects. Artist Thomas Kinkade's official tagline is Painter of Light. The late Dean Collins, co-founder of Finelight Studios, revolutionized how a whole generation of photographers learned and used lighting. I once attended a seminar called Captivated by the Light, run by photo guru Ed Pierce....

Studio Flash

If you're serious about using multiple flash units, a studio flash set-up might be more practical. The traditional studio flash is a multi-part unit, consisting of a flash head that mounts on your light stand, and is tethered to an AC or sometimes battery power supply. A single power supply can feed two or more flash heads at a time, with separate control over the output of each head. When they are operating offAC power, studio flash don't have to be frugal with the juice, and are often...

Determining Exposure

Calculating the proper exposure for an electronic flash photograph is a bit more complicated than determining the settings by continuous light. The right exposure isn't simply a function of how far away your subject is which the T2i can figure out based on the autofocus distance that's locked in just prior to taking the picture . Various objects reflect more or less light at the same distance so, obviously, the camera needs to measure the amount of light reflected back and through the lens....

Diffusing and Softening the Light

Direct light can be harsh and glaring, especially if you're using the flash built into your camera, or an auxiliary flash mounted in the hot shoe and pointed directly at your subject. The first thing you should do is stop using direct light unless you're looking for a stark, contrasty appearance as a creative effect . There are a number of simple things you can do with both continuous and flash illumination. Use window light. Light coming in a window can be soft and flattering, and a good...

Liquid Cleaning

Cleaning Sensor Canon 550d

Unfortunately, you'll often encounter really stubborn dust spots that can't be removed with a blast of air or flick of a brush. These spots may be combined with some grease or a liquid that causes them to stick to the sensor filter's surface. In such cases, liquid cleaning with a swab may be necessary. During my first clumsy attempts to clean my own sensor, I accidentally got my blower bulb tip too close to the sensor, and some sort of deposit from the tip of the bulb ended up on the sensor. I...

Picture Style Editor

The Picture Style Editor, shown in Figure 8.1, allows you to create your own custom Picture Styles, or edit existing styles, including the Standard, Landscape, Faithful, and other predefined settings already present in your Rebel T2i. You can change sharpness, contrast, color saturation, and color tone and a lot more and then save the modifications as a PF2 file that can be uploaded to the camera, or used by Digital Photo Professional described later in this chapter to modify a RAW image as it...

Evaluative metering

Exposure is calculated from a smaller central spot, about 3.8 percent of the image area. Center-weighted averaging metering. The T2i meters the entire scene, but gives the most emphasis to the central area of the frame. You'll find a detailed description of each of these modes in Chapter 4. You can easily switch between automatic and manual focus by moving the AF MF switch on the lens mounted on your camera. However, if you're using a Creative Zone shooting mode, you'll still...

Best Of Both Worlds

As I mentioned, if you're using a Basic Zone mode, the T2i selects the sRGB color space automatically. In addition, you may choose to set the sRGB color space with this menu entry to apply that gamut to all your Creative Zone photos as well. But, in either case, you can still easily obtain Adobe RGB versions of your photos if you need them. Just shoot using RAW JPEG. You'll end up with sRGB JPEGs suitable for output on your own printer, but you can still extract an Adobe RGB version from the...

Zoom or Prime

Zoom lenses have changed the way serious photographers take pictures. One of the reasons that I own 12 SLR film bodies is that in ancient times it was common to mount a different fixed focal length prime lens on various cameras and take pictures with two or three cameras around your neck or tucked in a camera case so you'd be ready to take a long shot or an intimate close-up or wide-angle view on a moment's notice, without the need to switch lenses. It made sense at the time to have a half...

Canon Picture Styles

Canon 550d Sharpness

Picture Styles are extremely flexible. Canon has set the parameters for the five predefined color Picture Styles and the single monochrome Picture Style to suit the needs of most photographers. But you can adjust any of those canned Picture Styles to settings you prefer. Better yet, you can use those three User Definition files to create brand new styles that are all your own. If you want rich, bright colors to emulate Velvia film or the work of legendary photographer Pete Turner, you can build...

Creative Zone Flash

When you're using a Creative Zone mode, you'll have to judge for yourself when flash might be useful, and flip it up yourself by pressing the Flash button on the side of the viewfinder hump. The behavior of the internal flash varies, depending on which Creative Zone mode you're using. P A-DEP. In these modes, the T2i fully automates the exposure process, giving you subtle fill flash effects in daylight, and fully illuminating your subject under dimmer lighting conditions. The camera selects a...

Snoots and Barn Doors

These fit over the flash unit and direct the light at your subject. Snoots are excellent for converting a flash unit into a hair light, while barn doors give you enough control over the illumination by opening and closing their flaps that you can use another flash as a background light, with the capability of feathering the light exactly where you want it on the background. A barn door unit is shown in Figure 7.23. Snoots and barn doors allow you to modulate the light from a flash or lamp, and...

Highlight tone priority

An external microphone is a good idea because the built-in microphone can easily pick up camera operation, such as the autofocus motor in a lens. Movie highlight tone priority. You can set highlight tone priority for movies independently of the setting you use for still photos. This option is available and visible only when Movie exposure is set to Manual. Choose Enable to improve highlight detail. Auto Lighting Optimizer will be disabled. Disable if you don't want to use this...

Three Ways to Take Long Exposures

There are actually three common types of lengthy exposures timed exposures, bulb exposures, and time exposures. The Rebel T2i offers only the first two, but once you understand all three, you'll see why Canon made the choices it did. Because of the length of the exposure, all of the following techniques should be used with a tripod to hold the camera steady. Timed exposures. These are long exposures from 1 second to 30 seconds, measured by the camera itself. To take a picture in this range,...

Highlight Tone Priority Limit

If you've enabled C.Fn II-06, Highlight tone priority, then only ISO 200-6400 will be selectable. If you've chosen Auto, instead, then the T2i will select an appropriate ISO value for you, based on the lighting conditions and the shooting mode you're using. Basic Zone modes except Portrait . Automatic ISO settings will range between ISO 100-3200. Basic Zone Portrait mode. ISO is fixed at ISO 100. Creative Zone modes. Automatic ISO settings will range between ISO 100-6400. When using electronic...

Working with Long Exposures

Long Exposures With Filter

Because the Rebel T2i produces such good images at longer exposures, and there are so many creative things you can do with long exposure techniques, you'll want to do some experimenting. Get yourself a tripod or another firm support and take some test shots with long exposure noise reduction both enabled and disabled to see whether you prefer low noise or high detail and get started. Here are some things to try Make people invisible. One very cool thing about long exposures is that objects that...

Focusing in Live View

Press the AE lock button to activate autofocus using the currently set Live View autofocus mode. Those modes are Quick mode, Live mode, and Face detection Live mode. You can also use manual focus. I'll describe each of these separately. This mode uses phase detection, as described earlier in the chapter. It temporarily interrupts Live View mode to allow the Rebel T2i to focus the same AF sensor used when you focus through the viewfinder. Because the step takes a second or so, you may get better...

Continuous Shooting

Eos 550d Continuous Shooting

The Canon EOS Rebel T2i's continuous shooting mode reminds me how far digital photography has brought us. The first accessory I purchased when I worked as a sports photographer some years ago was a motor drive for my film SLR. It enabled me to snap off a series of shots in rapid succession, which came in very handy when a fullback broke through the line and headed for the end zone. Even a seasoned action photographer can miss the decisive instant when a crucial block is made, or a baseball...

Contrast Detection

This is a slower mode, suitable for static subjects, and used by the Canon T2i with Live mode and Face detection Live mode. It's a bit easier to understand, and is illustrated by Figure 5.5. At top in the figure, the transitions between the edges found in the image are soft and blurred because of the low contrast between them. Although the illustration uses the same vertical lines used with the phase detection example, the orientation of the features doesn't matter. The focus system looks only...

How Electronic Flash Works

The bursts of light we call electronic flash are produced by a flash of photons generated by an electrical charge that is accumulated in a component called a capacitor, and are then directed through a glass tube containing xenon gas, which absorbs the energy and emits the brief flash. For the pop-up flash built into the Rebel T2i, the full burst of light lasts about 1 1,000th second and provides enough illumination to shoot a subject 10 feet away at f 4 using the ISO 100 setting. In a more...

EyeFi firmware Ver

If the card does not locate your wireless network, consult the instructions that came with the Eye-Fi card to link up. 7. Once you're connected, the Transmission Status icon will appear to the left of the battery check symbol on the T2i's LCD information screen. See Figure 5.30. It's appearance will indicate the current status Blinking. Connecting to access point. Solid black. Connection established. Solid with up arrow icon. Transmission in progress. The Transmission Status icon appears on...

Capturing Video Sound

To shoot movies with your camera, just follow these steps 1. Change to Movie mode. Set the Mode Dial to the Movie setting turn the dial as far as it will go in a clockwise direction . 2. Focus. Use the autofocus or manual focus techniques described in the preceding sections to achieve focus on your subject. As before, you can activate the current AF mode by pressing the AE lock button. 3. Begin filming. Press the Live View button to begin shooting. A red dot appears in the upper-right corner of...

Adep And Hyperfocal Distance

Canon 550d Display Raw Jpeg Quality Mode

A-DEP is a simplified version of a related mode found in some higher-end Canon digital and film models called DEP. DEP allows you to manually select the nearest and farthest points you want in focus, and the camera will then adjust the focus point to a setting known as the hypefocal distance. At the hyperfocal distance, everything from half that distance to infinity will be in acceptable focus. Although many photographers elect to set hyperfocal distance themselves, the exact distance varies by...

Prevention

One of the nice things about modern electronic cameras like the Canon EOS Rebel T2i is that they have fewer mechanical moving parts to fail, so they are less likely to wear out. No film transport mechanism, no wind lever or motor drive, no complicated mechanical linkages from camera to lens to physically stop down the lens aperture. Instead, tiny, reliable motors are built into each lens and you lose the use of only that lens should something fail , and one of the few major moving parts in the...

Warning

Delkin Skin For T2i

Use a fully charged battery or Canon's optional ACK-E5 AC adapter kit to ensure that you'll have enough power to operate the camera for the entire upgrade. Moreover, you should not turn off the camera while your old firmware is being overwritten. Don't open the memory card door or do anything else that might disrupt operation of the T2i while the firmware is being installed. 1. Download the firmware from Canon you'll find it in the Downloads section of the Support portion of Canon's website and...

Low Level Format

You can also press the Trash button, located in the lower-right corner of the back of the camera, to mark the Low level format box on the Format screen. This tells the T2i to perform an additional, more thorough, formatting of the card after the initial format is finished. The low level format serves to remove data from all writable portions of your memory card while locking out bad sectors, and can be used to restore a memory card that is slowing down as it trips over those bad sectors. This...

Or Choose Focus Mode In Menu

You can also select the Live View focus mode using the Live View function settings option in the Set-up 2 menu. 4. Choose AF point. With the nine focus points illuminated, rotate the Main Dial to choose which of the nine AF points to use. They turn blue on the screen when active. 5. Select subject. Compose the image on the LCD so the selected focus point is on the subject. 6. Press and hold the AE lock button. The LCD will blank as the mirror flips down, reflecting the view of the subject to...

Avoiding Potential Wide Angle Problems

Fisheye Lens Canon Rebel T2i

Wide-angle lenses have a few quirks that you'll want to keep in mind when shooting so you can avoid falling into some common traps. Here's a checklist of tips for avoiding common problems Symptom converging lines. Unless you want to use wildly diverging lines as a creative effect, it's a good idea to keep horizontal and vertical lines in landscapes, architecture, and other subjects carefully aligned with the sides, top, and bottom of the frame. That will help you avoid undesired perspective...

Your Second and Third Lens

There are really only two advantages to owning just a single lens. One of them is creativity. Keeping one set of optics mounted on your T2i all the time forces you to be especially imaginative in your approach to your subjects. I once visited Europe with only a single camera body and a 35mm f 2 lens. The experience was actually quite exciting, because I had to use a variety of techniques to allow that one lens to serve for landscapes, available light photos, action, close-ups, portraits, and...

Avoiding Sync Speed Problems

Using a shutter speed faster than 1 200th second can cause problems. Triggering the electronic flash only when the shutter is completely open makes a lot of sense if you think about what's going on. To obtain shutter speeds faster than 1 200th second, the T2i exposes only part of the sensor at one time, by starting the second curtain on its journey before the first curtain has completely opened, as shown in Figure 7.9. That effectively provides a briefer exposure as the open slit between the...

Sensor Cleaning

Those new to the concept of sensor dust actually hesitate before deciding to clean their cameras themselves. Isn't it a better idea to pack up your T2i and send it to a Canon service center so their crack technical staff can do the job for you Or, at the very least, shouldn't you let the friendly folks at your local camera store do it Of course, if you choose to let someone else clean your sensor, they will be using methods that are more or less identical to the techniques you would use...

Displaying Histograms

Canon Histogram

To view histograms on your screen, press the DISP button while an image is shown on the LCD. Keep pressing the button until the histogram s are shown. The display will cycle between several levels of information, including flashing highlights and two histograms. One histogram shows overall brightness levels Figure 4.24 , while the second type of histogram screen shows both brightness levels and levels for each of the red, green, and blue channels see Figure 4.25 . During histogram display,...

But Dont Forget the Crop Factor

T2i Crop Factor

From time to time you've heard the term crop factor, and you've probably also heard the term lens multiplier factor. Both are misleading and inaccurate terms used to describe the same phenomenon the fact that cameras like the Rebel T2i and most other affordable digital SLRs provide a field of view that's smaller and narrower than that produced by certain other usually much more expensive cameras, when fitted with exactly the same lens. Figure 6.1 quite clearly shows the phenomenon at work. The...

External Flash Function Setting

Canon Harici Fla Ayarlar

This menu is available only when you have a compatible dedicated Canon Speedlite electronic flash attached and switched on. The settings available with the 580 EX II and 430 EX are shown in Figure 7.12. If you press the DISP button while adjusting flash settings, both the changes made to the settings of an attached external flash and to the built-in flash will be cleared. Flash mode. This entry allows you to set the flash mode for the external flash, from E-TTL II, A-TTL, or TTL. All three...

Ghost Images

The difference between triggering the flash when the shutter just opens, or just when it begins to close might not seem like much. But whether you use first-curtain sync the default setting or second-curtain sync an optional setting can make a significant difference to your photograph if the ambient light in your scene also contributes to the image. At faster shutter speeds, particularly 1 200th second, there isn't much time for the ambient light to register, unless it is very bright. It's...

Telephotos and Bokeh

Bokeh describes the aesthetic qualities of the out-of-focus parts of an image and whether out-of-focus points of light circles of confusion are rendered as distracting fuzzy discs or smoothly fade into the background. Boke is a Japanese word for blur, and the h was added to keep English speakers from rendering it monosyllabically to rhyme with broke. Although bokeh is visible in blurry portions of any image, it's of particular concern with telephoto lenses, which, thanks to the magic of reduced...

Dust the FAQs Maam

Cluster Defect Stuck Pixel

Here are some of the most frequently asked questions about sensor dust issues. Q. I see tiny specks in my viewfinder. Do I have dust on my sensor A. If you see sharp, well-defined specks, they are clinging to the underside of your focus screen and not on your sensor. They have absolutely no effect on your photographs, and are merely annoying or distracting. Q. I can see dust on my mirror. How can I remove it A. Like focus screen dust, any artifacts that have settled on your mirror won't affect...

Phase One Capture One Pro C

If there is a Cadillac of RAW converters for Nikon and Canon digital SLR cameras, C1 Pro has to be it. This premium-priced program does everything, does it well, and does it quickly. If you can't justify the price tag of this professional-level software, there are lite versions for serious amateurs and cash-challenged professionals called Capture One5. Aimed at photographers with high volume needs that would include school and portrait photographers, as well as busy commercial photographers ,...

Self Timer

The Rebel T2i has a built-in self-timer with 10-second and 2-second delays. Remember that the 10-second timer can also be used with a remote control and is marked with a remote icon in the drive mode screen. Your camera also has a self-timer multiple setting that allows taking 2 to 10 shots after the delay. All these options were described in Chapter 2. Activate the timer by pressing the Drive button left cross key and pressing the left right cross keys to choose one of the three self-timer...

Hi

This entry in the Shooting 1 menu see Figure 3.5 gives you the ability to snap off pictures without a memory card installed or to lock the camera shutter release if that is the case. It is sometimes called Play mode, because you can experiment with your camera's features or even hand your T2i to a friend to let him fool around, without any danger of pictures actually being taken. Back in our film days, we'd sometimes finish a roll, rewind the film back into its cassette surreptitiously, and...

Phase Detection

500d Cross Autofocus Sensor

In this mode, the autofocus sampling area is divided into two halves by a lens in the sensor. The two halves are compared, much like actually, exactly like a two-window rangefinder used in surveying, weaponry, and non-SLR cameras like the venerable Leica M film models. The contrast between the two images changes as focus is moved in or out, until sharp focus is achieved when the images are in phase, or lined up. The T2i's nine autofocus sensors are located in the floor of the mirror box, just...

Filters Vs Toning

Canon 550d Highlight Tone Priority Raw

Although some of the color choices overlap, you'll get very different looks when choosing between filter effects and toning effects. Filter effects add no color to the monochrome image. Instead, they reproduce the look of black-and-white film that has been shot through a color filter. That is, yellow will make the sky darker and the clouds will stand out more, while orange makes the sky even darker and sunsets more full of detail. The red filter produces the darkest sky of all and darkens green...

T2i Built In Flash Setting Gray

Red-eye is tamed right , thanks to the Rebel T2i's redeye reduction lamp. This multi-level menu entry, creatively moved to this location from its slot in the Setup 2 menu in earlier Rebel models, includes five settings for controlling the Canon EOS Rebel T2i's built-in, pop-up electronic flash unit, as well as accessory flash units you can attach to the camera see Figure 3.12 . Here are your main options. Use this option to enable or disable the built-in or attached accessory electronic flash...

Adding Circles of Confusion

But there are other factors in play, as well. You know that increased depth-of-field brings more of your subject into focus. But more depth-of-field also makes autofocusing or manual focusing more difficult because the contrast is lower between objects at different distances. So, autofocus with a 200mm lens or zoom setting may be easier than at a 28mm focal length or zoom setting because the longer lens has less apparent depth-of-field. By the same token, a lens with a maximum aperture of f 1.8...

Adobe Photoshop

The latest version of Photoshop includes a built-in RAW plug-in that is compatible with the proprietary formats of a growing number of digital cameras, both new and old. This plug-in also works with Photoshop Elements. To open a RAW image in Photoshop, just follow these steps Elements users can use much the same workflow, although fewer settings are available 1. Transfer the RAW images from your camera to your computer's hard drive. 2. In Photoshop, choose Open from the File menu, or use...
