Canon EOS Rebel T2i/550D Digital Field Guide Roadmap to the Rebel T2i/550D
If you’ve been using the Rebel T2i/550D, then you already know that the most frequently used camera controls are located within finger’s reach for quick adjustments
as you’re shooting. Less frequently used functions are accessible from the camera
menus. The following sections will familiarize you with the T2i/550D controls and their
names — names that are used throughout the book. You can refer back to these figures as you read the book to locate the controls you need.
Front camera controls
On the front of the camera, the controls that you’ll use most often are the Lens
Release button and the Depth-of-Field Preview button. And, of course, you’ll use the
lens mount each time you change lenses.

Chapter 1 Setting Up the EOS Rebel T2i/550D
From bottom left to top right, here is a look at the front of the camera:
X
Grip/Battery compartment. This is the molded area where your hand grips the
camera, and it serves as the battery compartment as well.
X
Remote control sensor. This sensor works with the accessory Remote Control
RC-6 that can fire the camera’s shutter from up to 16.4 feet (five meters) from
the camera. The remote includes the options for immediate or a 2-second delay
before shutter firing.
X
Shutter button. Press this button halfway down to focus on the subject, and
then press it completely to make the picture. In addition, when you half-press
the Shutter button, the camera sets the aperture and shutter speed based on
the current ISO. You’ll learn more about focusing and exposure in Chapter 2.
X
Reflex mirror. This mirror provides a view of the scene when you’re composing
the image in the viewfinder, and when you press the Shutter button completely,
it flips up and out of the optical path to expose the image sensor to make the
picture.
X
Lens contacts. These contacts provide communication between the lens and
the camera.
X
Lens Release button. Press this button to release the lens from the lens mount,
and then turn the lens to remove it.
X
Depth-of-Field Preview button. Press this button to stop down, or adjust, the
lens diaphragm to the current aperture (f-stop) so that you can preview the depth
of field in the viewfinder. The larger the area of darkness in the viewfinder, the
more extensive the depth of field will be. You can also use this button when
shooting in Live View. While you press the Depth-of-Field Preview button, you
can’t change the aperture.
At the lens’s maximum aperture, the Depth-of-Field Preview button cannot be
depressed because the camera’s diaphragm is fully open. The maximum aperture is the widest lens opening for the lens you’re using and it varies by lens.
NOTE
X
Flash button. Pressing this button in P, Tv, Av, M, and A-DEP shooting modes
pops up the built-in flash.
X
Built-in microphone. The built-in monoaural microphone records sound when
you’re shooting movies.
X
EF and EF-S lens mount index markers. The lens mount has a red and a white
mark for two types of lenses. The white mark on the lens mount is for Canon EF-S
lenses that have a white mark on the lens barrel. EF-S lenses are designed for the
3
Canon EOS Rebel T2i/550D Digital Field Guide smaller sensor size of the T2i/550D. The red mark on the lens mount is for Canon
EF lenses. EF lenses can be used on any Canon EOS camera. Just set the lens on
the lens mount and line up the white or red mark on the lens barrel with the same
color mark on the lens mount, and then turn the lens to the right to attach it.
X
Built-in flash. The flash provides illumination either as the main light source or
as a fill flash. In Basic Zone shooting modes such as Full Auto, Portrait, and so
on, the flash fires automatically. In Creative Zone shooting modes including P,
Tv, Av, M, and A-DEP, you have to press the Flash pop-up button to use the
built-in flash.
X
Red-eye reduction/Self-timer lamp. When you have Red-eye reduction turned
on, this lamp lights to help reduce the size of the subject’s pupils to minimize
the appearance of red-eye in the final image.
Top camera controls
Controls on the top of the camera enable you to use your thumb and index finger on
your right hand to control common adjustments quickly. Here is a look at the top of
the camera.

X
Focal plane mark. This is the point from which the lens’ minimum focusing
distance is measured.
X
Hot shoe. You can mount an accessory Speedlite flash unit here to provide communication between the flash and the Rebel.
X
Mode dial. Turning this dial changes the shooting mode. Just line up the shooting mode you want to use with the white mark beside the dial.
X
Power switch. This button switches the camera on and off.
X
ISO speed button. Pressing this button displays the ISO speed screen on the
LCD so that you can change the ISO setting, which determines the sensor’s
sensitivity to light. In P (Program AE), Tv (Shutter-Priority), Av (Aperture-Priority),
M (Manual), and A-DEP shooting modes, you can select Auto ISO to have the
camera automatically determine the ISO from 100 to 6400, or you can set the
ISO yourself. In all automatic shooting modes such as Portrait and Landscape,
the camera automatically sets the ISO between 100 and 3200. Alternately, you
can set the highest ISO setting that the Auto ISO option uses. You can also turn
on an additional high ISO setting, equivalent to 12800 by setting Custom
Function I-2.

Canon EOS Rebel T2i/550D Digital Field Guide Rear camera controls
The controls on the back of the Rebel T2i/550D enable you to make quick adjustments
while you’re shooting. Some of the rear camera controls can be used only in P, Tv, Av,
M, and A-DEP shooting modes. In automatic camera modes such as Portrait,
Landscape, and Sports, the camera sets all of the settings for you, so pressing the AV,
WB, and Drive mode selection buttons has no effect. But in P, Tv, Av, or M, and
A-DEP shooting modes, these buttons function as described in the following list.
If you’re shooting and press a button and nothing happens, check the Mode
dial to see if you’re using an automatic mode such as Portrait or Landscape. If

Chapter 1 Setting Up the EOS Rebel T2i/550D
Depending on the lens, additional controls may include the following:
X
Focusing distance range selection switch. This switch determines and limits
the range that the lens uses when seeking focus to speed up autofocusing. The
focusing distance range options vary by lens.
X
Image Stabilizer switch. This switch turns Optical Image Stabilization on or off.
Optical Image Stabilization (IS) corrects vibrations at any angle when handholding the camera and lens. IS lenses typically allow sharp handheld images of two
or more f-stops over the lens’s maximum aperture.
X
Stabilizer mode switch. Offered on some telephoto lenses, this switch has
two modes: one mode for standard shooting and one mode for vibration correction when panning at right angles to the camera’s panning movement.
X
Zoom ring. The zoom ring adjusts the lens in or out to the focal lengths marked
on the ring.
X
Focusing ring. For lenses that have a focusing mode switch, the lens focusing
ring can be used at any time regardless of focusing mode by switching to MF on
the side of the lens, and then turning this ring to focus.
X
Distance scale and infinity compensation mark. This shows the lens’s minimum focusing distance to infinity. The infinity compensation mark compensates
for shifting the infinity focus point resulting from changes in temperature. You
can set the distance scale slightly past the infinity mark to compensate.
The LCD
With the T2i/550D, the 3-inch LCD not only displays captured images and current camera settings, but it also provides a live view and focusing screen with Live View and
Movie mode shooting. The LCD displays 100 percent coverage of the scene.
Viewfinder display
On the Rebel T2i/550D, the optical, eye-level pentamirror viewfinder displays approximately 95 percent of the scene that the sensor captures. In addition, the viewfinder
displays the AF points, a 4-percent Spot metering circle that is displayed at the center
of the viewfinder, as well as information at the bottom that displays the current shooting settings, a focus confirmation light, and other settings.

Canon EOS Rebel T2i/550D Digital Field Guide Setting Up the Rebel T2i/550D
You may have already set up basic settings such as the date and time. But be sure to
check through this section of the book for settings that you may have missed or want
to revise. The settings that I recommend are designed to get the highest resolution
images that you can print at full size to take advantage of all the high resolution that
the T2i/550D offers.
Many people are afraid that changing camera settings will “mess up” the pictures that
they’re getting, and that they won’t know how to reset the camera if they don’t like
the changes they’ve made. Canon provides a reset option, which means that you can
always revert to the original settings on the Rebel T2i/550D so that you can start fresh.
To reset the camera to the original settings, follow these steps.
1. Press the Menu button, and then press the right cross key to select the
Setup 3 menu.
2. Press the down cross key to select Clear settings, and then press the Set
button.
3. To reset the camera to factory settings, press the up or down cross key to
select Clear all camera settings, and then press the Set button. The Clear all
camera settings confirmation screen appears.
4. Press the right cross key to select OK.
About Media Cards
The Rebel T2i/550D accepts SD and SDHC, or Secure Digital High Capacity, SDXC,
and Eye-Fi SD media cards. Not all media cards are created equal, and the type and
speed of media that you use affects the Rebel T2i/550D’s response and performance
times including how quickly images are written to the media card, and your ability to
continue shooting during the image-writing process. Memory card speed also affects
the speed at which images display on the LCD, and how quickly you can enlarge
images on the LCD. And with the high-definition video capability of the Rebel, Canon
recommends using a Class 6 or higher media card.
In addition, the T2i/550D accepts SDXC memory cards that offer the potential for
increased storage capacity over previous SD cards. Eye-Fi SD cards have a built-in Wi-Fi
transmitter and internal antenna for wireless, high-speed transfer of images and video
from the camera to the computer or to online Web sites from Wi-Fi-enabled locations
or from your network. Eye-Fi also supports geotagging and uploading RAW files.
14
Chapter 1 Setting Up the EOS Rebel T2i/550D
At this writing, SDXC cards are not supported by all computer operating systems.
If you insert the card into a computer or card reader and receive a mesCAUTION
sage asking you to format the card, choose Cancel to avoid overwriting the SDXC
format. For more information, visit the www.sdcard.org/developers/tech/sdxc/using_
sdxc Web site.
The type of file format that you choose also affects the speed of certain tasks. For
example, when writing images to the media card, JPEG image files write to the card
faster than RAW or RAW + Large JPEG files. JPEG and RAW file formats are discussed in detail later in this chapter.
As you take pictures, the LCD on the Rebel T2i/550D shows the approximate number
of images that remain on the media card. The number is approximate because each
image varies slightly, depending on the ISO setting, the file format and resolution, the
Picture Style, and the image itself (different images compress differently). And as you
shoot video, the Rebel displays the recording time on the LCD. Video recording shuts
off automatically when the size of the movie file reaches 4GB. For still and video
shooting, an 8GB card is a good size to consider.
When you buy a new memory card, always format it in the camera and never on your
computer. But first off-load all images to the computer because formatting erases
images even if you’ve set protection on them. Also be sure to format cards that you’ve
used in other cameras when you begin using them in the Rebel T2i/550D. Formatting
a media card in the camera also cleans any image-related data freeing up space on the
card, and it manages the file structure on the card so the Rebel T2i/550D and media
card work properly together.
To format a card in the camera, be sure that you download all images to your computer first, and then follow these steps:
1. Press the Menu button, and then turn the Main dial to select the Setup 1
menu.
2. Press the down or up cross key to select Format, and then press the Set
button. The Format screen appears asking you to confirm that you want to format the card and lose all data on the card.
You can optionally choose the Low-level format option that erases the recordable sectors on the card. While Low-level format takes a bit longer, it can
improve the performance of the card, and it ensures that all information on the
card is permanently erased.
15
Canon EOS Rebel T2i/550D Digital Field Guide 3. To do a low-level format, press the Erase button to place a check mark next
to Low level format, and then press the right cross key to select OK.
4. Press the Set button. The camera formats the card, and then displays the
Setup 1 menu.
It is generally a good idea to format media cards every few weeks to keep them clean.
To avoid taking pictures when no memory card is in the camera, press the
Menu button, choose the Shooting 1 menu, and then press the down cross
NOTE
key to select Release shutter without card. Press the Set button, press the down
cross key to select Disable, and then press the Set button again. Now you cannot
release the shutter unless a media card is in the camera.
Avoid Losing Images
When the camera’s red access light — located on the back of the camera — is
blinking, it means that the camera is recording or erasing image data. When the
access light is blinking, do not open the SD card slot cover, do not attempt to
remove the media card, and do not remove the camera battery. Any of these
actions can result in losing images and damage to the media card. There is an
audible warning to let you know that images are being written to the card, but
make it a habit to watch for the access light anyway to know not to open the
media card slot cover or turn off the camera.
Choosing the File Format and Quality
The file format, either JPEG or RAW, and the JPEG quality level that you choose determine not only the number of images that you can store on the media card, but also the
sizes at which you can later print images from the Rebel T2i/550D.
The Rebel T2i/550D delivers very high-quality images that make beautiful prints at
approximately 14.5 × 21.6 inches. Even if you don’t foresee printing images any larger
than 4 × 5 inches, you may get a once-in-a-lifetime shot and want to print it as large as
possible. For this reason, and to take advantage of the Rebel T2i/550D’s fine image
detail and high resolution, you’ll want to choose a high-quality setting and leave it
there for all your shooting. The high image-quality settings take more space on the
media card, but the price of the card is small compared to missing out on a great
image that you can’t print at the maximum image size.
16
Chapter 1 Setting Up the EOS Rebel T2i/550D
The JPEG quality options on the Rebel T2i/550D are displayed with icons on the
Quality screen that indicate the compression level of the files and the recording size.
For example, a solid quarter circle and the letter “L” indicate the largest JPEG file size
and the solid quarter circle indicates the lowest level of file compression for the highest image quality. Likewise, a jagged quarter circle indicates higher compression levels and relatively lower quality, and “M” indicates medium quality. File formats and
compression are discussed next.
JPEG format
JPEG, an acronym for Joint Photographic Experts Group, is a popular file format for
digital images that provides not only smaller file sizes than the RAW files, but it also
offers the advantage of being able to display your images straight from the camera on
any computer, on the Web, and in e-mail messages. To achieve the small file size,
JPEG compresses images, and, in the process, it discards some data from the image —
typically data that you would not easily see. This characteristic of discarding image
data during compression gains JPEG its lossy moniker. The amount of data discarded
depends on the level of JPEG compression. High compression levels discard more
image data than low levels. The higher the compression level, the smaller the file size
and the more images that you can store on the media card, and vice versa.
As the compression level increases to make the file size smaller, more of the original
image data is discarded, and the image quality degrades. Compression also introduces
defects, referred to as artifacts, which can create a blocky, jagged look, blurring, and
diminished color fidelity in the image. At low compression levels, artifacts are minimal, but as the level increases, they become more noticeable and objectionable. You’ll
see the effects of high compression ratios when you enlarge the image to 100 percent in an image-editing program on the computer. To get the highest-quality images,
use the lowest compression and the highest quality settings, such as Large/Fine. If
space on the card is tight, then use the next lower setting, Large/Normal. If you use
lower quality settings, just be aware that the image quality diminishes accordingly.
If you edit JPEG images in an editing program, image data continues to be discarded each time you save the file. I recommend downloading JPEG files to
the computer, and then saving them as TIFF (Tagged Image File Format) or PSD
(Photoshop’s file format) files. TIFF and PSD, available in Adobe’s Photoshop imageediting program, are lossless file formats.
TIP
When you shoot JPEG images, the camera’s internal software processes, or edits,
the images before storing them on the media card. This image preprocessing is an
advantage if you routinely print images directly from the SD card, and if you prefer not
17
Canon EOS Rebel T2i/550D Digital Field Guide to edit images on the computer. And because the T2i offers a variety of Picture Styles
that change the way that image contrast, saturation, sharpness, and color are rendered, you can get very nice prints with no editing on the computer.
The JPEG quality options reflect the megapixels recorded for the image. At the Large
settings, images are recorded at 17.9 megapixels. The Medium quality options record
8 megapixels, while Low quality options record 4.5 megapixels.
Picture Styles are detailed in Chapter 3.
CROSS REF
RAW format
RAW files store image data directly from the camera’s sensor to the media card with
a minimum of in-camera processing. Unlike JPEG images, which you can view in any
image-editing program, you must view RAW files using the Canon Image Browser,
Digital Photo Professional, or another RAW-compatible program such as Adobe Bridge
and Camera Raw. Most operating systems, such as the Mac, provide regular updates
so that you can view RAW images on your computer without first opening them in a
RAW conversion program. To print and share RAW images, you must first convert
them by using a program that supports the T2i/550D’s RAW file format, and then save
them as a TIFF or JPEG file. You can use Canon’s Digital Photo Professional program
or a third-party RAW-conversion program to convert RAW images.
With all these caveats, you may wonder why you’d choose RAW shooting. The answer
is simple and compelling — RAW files offer the highest image quality and the ultimate
flexibility in correcting and perfecting the final image. With RAW images, you can
change key camera settings after you take the picture. For example, if you didn’t set
the correct white balance or exposure, you can change it when you convert the image
on the computer.
TIP
Canon includes its Digital Photo Professional program on the disc included in
the Rebel T2i/550D box, and that program enables you to convert RAW files.
In addition, you can adjust the image brightness, contrast, and color saturation — in
effect, you have a second chance to correct underexposed or overexposed images,
and to correct the color balance, contrast, and saturation after you take the picture.
The only camera settings that the Rebel T2i/550D applies to RAW files are aperture,
ISO, and shutter speed. Other settings such as White balance, Picture Style, and so
on are “noted,” but not applied to the file. As a result, you have a great deal of control
over how image data looks when you convert a RAW image.
18
Chapter 1 Setting Up the EOS Rebel T2i/550D
Because RAW is a lossless format (no loss of image data), image quality is not
degraded by compression. However, RAW files are larger, so you can store fewer
RAW images on the media card than JPEG images.
RAW files are denoted with a .CR2 file name extension. After converting the RAW
data, you can save the image in a standard file format such as TIFF or JPEG.
RAW + JPEG
On the Rebel T2i/550D, you can also choose to capture both RAW and Large/Fine JPEG
images simultaneously. The RAW+JPEG option on the image Quality screen is handy
when you want the advantages that RAW files offer, and you also want a JPEG image
to quickly post on a Web site or to send in e-mail. If you choose RAW+JPEG, both
images are saved in the same folder with the same file number but with different file
extensions. RAW files have a .CR2 extension, and JPEG files have a .JPG extension.
To set the image quality, follow these steps:
1. Press the Menu button, and then turn the Main dial to select the Shooting
1 menu.
2. Press the down or up cross key to select Quality.
3. Press the Set button. The Quality screen appears with the currently selected
quality setting displayed along with the image dimensions in pixels and the approximate number of images you can store on the current media card in the camera.
4. Press the right or left cross key to select the size and quality that you want.
5. Press the Set button.
Changing File Numbering
When you begin shooting images, the
Rebel T2i/550D automatically creates a
folder on the SD/SDHC card to store the
images. The folder is named 100Canon,
and you see the folder when you download images from the camera to the
computer. In addition, the camera numbers the images and assigns prefixes
and file extensions. Both JPEG and RAW
files begin with the prefix IMG_. Movie
files begin with MVI_ and have a .MOV
file extension.

1.7 The File numbering options screen
19
Canon EOS Rebel T2i/550D Digital Field Guide While much of the file management on the camera is automatic, you can choose how
the camera numbers images, and your choice can help you manage images on your
computer. The file numbering options are: Continuous, Auto reset, and Manual reset.
Here is how each file numbering option works.
Continuous file numbering
When you begin using the T2i/550D, the camera automatically numbers images
sequentially. When you replace the media card, the camera remembers the last highest image number and continues numbering from the last file number. Images are
numbered sequentially using a unique, four-digit number from 0001 to 9999. The camera continues sequential numbering until you shoot image number 9999. At that point,
the camera creates a new folder named 101, and images you shoot restart with number 0001.
This file-numbering sequence continues uninterrupted until you insert a memory card
that already has images on it. At that point, the T2i/550D notes the highest file number
on the media card, and then uses the next higher number when you take the next
image — provided that the number is higher than the highest image number stored in
the camera’s memory. Stated another way, the camera uses the highest number that
is either on the media card or that is stored in the camera’s internal memory. Then the
camera uses that number to continue file numbering. If it is important to you that files
be numbered consecutively, then be sure to insert formatted/empty media cards into
the camera.
An advantage of Continuous file numbering is that, to a point, this file-numbering option
ensures unique file names, making managing and organizing images on the computer
easier because there is less chance that images will have duplicate file names.
Now is a good time to create a system of image folders on your computer. I
know from experience that the time spent creating a solid file system for storing images pays big dividends over time.
TIP
Auto reset
With this file-numbering option, you can have the file number restart with 0001 each
time you insert a different media card. If the media card has images stored on it, then
numbering continues from the highest image number stored on the card. So if you
want the images to always begin at 0001 on each media card, then be sure to insert a
freshly formatted media card each time you replace the card.
20
Chapter 1 Setting Up the EOS Rebel T2i/550D
If you like to organize images by media card, Auto Reset is a good option. However,
be aware that multiple images that you store on the computer will have the same file
name. This means that you should create separate folders on the computer and follow
scrupulous folder organization to avoid file name conflicts and potential overwriting of
images that have the same file name.
Manual reset
If you choose Manual reset, then the camera first creates a new folder on the media
card, and then it saves images to the new folder starting with file number 0001. After
Manual reset, file numbering returns to Continuous or Auto reset — whichever option
you used previously.
The Manual reset option is handy if you want the camera to create separate folders for
images that you take over a span of several days.
On the Rebel T2i/550D, up to 999 folders can be created automatically by the camera
with up to 9,999 images stored in each folder. If you reach these capacities, a message appears telling you to change the media card even if there is room remaining on
it. Until you change the media card, you can’t continue shooting.
To change the file-numbering method on the T2i/550D, follow these steps:
1. Press the Menu button, and then turn the Main dial to select the Setup 1
menu.
2. Press the down or up cross key to select File numbering, and then press
the Set button. Three file-numbering options appear with the current setting
highlighted.
3. Press the down cross key to select Continuous, Auto reset, or Manual
reset, and then press the Set button. The option you choose remains in effect
until you change it with the exception of Manual reset as noted previously.
Additional Setup Options
There are a number of handy setup options that can make your shooting easier and
more efficient. You may have already set some of these options, but in case you
missed some, you can check Table 1.1 and see which ones you want to set or change.
21
Canon EOS Rebel T2i/550D Digital Field Guide The additional setup options are typically those that you set up only once, although
there are some that you may revisit in specific shooting scenarios. For example, I prefer to turn on the autofocus confirmation beep in most shooting situations. But at a
wedding or event when the sound of the beep is intrusive, I turn it off.
Also, you may prefer to have vertical images automatically rotated on the LCD to the
correct orientation. However, this rotation makes the LCD image smaller, so you may
prefer to rotate vertical images only for computer display.
Table 1.1 provides a guide for these additional setup options. If you don’t see an
option listed in the table, check to see which shooting mode you’ve set on the Mode
dial. Some options are not available in the automatic shooting modes such as Portrait,
Landscape, Sports, and so on. If an option isn’t available, just change the Mode dial to
P, Tv, Av, M, or A-DEP to access the option. In other instances, the options are detailed
in later chapters of this book.
To change these options, press the Menu button, and then follow the instructions in
the subheadings in Table 1.1.

8. Press the Playback button. Images are displayed on the TV but not on the camera’s LCD monitor. When you finish viewing images, turn off the TV and the
camera before disconnecting the cables.
You can use the previous steps to not only display images stored on the media
card on the TV, but also to use the TV to display what would appear on the LCD
during both general shooting and when you’re shooting in Live View.
TIP
Erasing and Protecting Images
For those who keep multiple images on media cards for prolonged periods of time, it’s
important to use options on the T2i/550D that enable you to delete images you don’t
want, and to protect images you do want from accidental deletion. The following sections detail how to erase one or multiple images and how to protect images.
Erasing images
Erasing images is useful provided that you are certain that you don’t want the image.
From experience, I know that some images that appear to be mediocre on the LCD
can very often be salvaged with judicious image editing on the computer. For that
reason, I recommend erasing images with caution.
With the Rebel T2i/550D, you can choose to erase images one at a time or you can
select individual images to erase, or you can erase all images on the media card. If you
want to delete one image at a time, follow these steps:
1. Press the Playback button on the back of the camera, and then press the
left and right cross keys to select the picture that you want to delete.
2. Press the Erase button, and then press the right cross key to select Erase.
3. Press the Set button to erase the image. When the access lamp stops blinking, lightly press the Shutter button to continue shooting.

5. Press the left or right cross key to move to the next image, and repeat Step
4. Continue this process until all the images you want to delete are marked with
a check mark.
6. Press the Erase button on the back of the camera. The Erase images screen
appears with a confirmation message asking if you want to erase the selected
images.
7. Press the right cross key to select OK, and then press the Set button. All
check-marked images are erased.
Protecting images
To ensure that important images are not accidentally deleted, you can protect them.
Setting protection means that no one can erase the image when using the erase
images options.
CAUTION
Even protected images are erased if you or someone else formats the media
card.
You can protect an image by following these steps:
1. Press the Menu button, and then turn the Main dial to select the Playback
1 menu.
2. Press the up or down cross key to select Protect images, and then press
the Set button. The last image taken is displayed on the LCD with a protection
and a SET icon in the upper-right corner. If this isn’t the image you want to protect, press the left or right cross key to display the image you want to protect.
