✦
Erase button. Press this button to
delete the current image during
image playback.
Within the circle at the back right of the
Rebel XSi/450D are four buttons, collectively
referred to as cross keys. The cross key func-
tions change depending on whether you’re
playing back images, navigating camera
menus, or changing exposure settings.
For example, when you play back images,
the left and right cross keys move backward
and forward through the images stored on
the SD/SDHC card; and when you navigate
through menu options, the cross keys move
to the option you want.
✦
Drive mode selection. Press the
left cross key to set the Rebel
XSi/450D to shoot one picture at a
time, or to shoot continuously at
3.5 frames per second (fps). The
maximum burst during continuous
shooting is approximately 53
Large/Fine JPEG frames, six RAW
frames, or four RAW +Large/Fine
JPEG frames. You can also use this
button to select one of the Self-
timer/remote control modes.
During image playback, press this
button to move to a previous
image.
✦
Picture Style. Press the down
cross key to display the Picture
Style screen where you can choose
a style or “look” that varies the
image contrast, color rendition, sat-
uration, and sharpness. You can
choose the Standard, Portrait,
Landscape, Neutral, Faithful, or
Monochrome Picture style and
customize up to three User
Defined Picture Styles.
✦
AF (Autofocus) mode. Press the
right cross key (labeled as AF) to
choose among three autofocus
modes: One-shot for still subjects,
AI Focus for subjects that may start
to move or move unpredictably
such as kids and wildlife, or AI
Servo, which tracks focus of mov-
ing subjects. During image play-
back, press this button to move to
the next image.
✦
Metering mode selection. Press
the up cross key to choose a
metering mode that determines
how much of the scene that the
camera uses to meter subject
brightness. The default Evaluative
metering system takes into account
the entire scene and is accurate for
even backlit subjects. Spot meter-
ing uses the center four percent of
the viewfinder, indicated by the cir-
cle etched in the viewfinder, to
measure subject brightness. Partial
metering weights the metering at
the center of the viewfinder, and
Center-weighted Average weights
metering throughout the scene but
gives more weight to the center.
✦
Set button. Press this button to
confirm changes you make on the
camera menus, and to display sub-
menus. You can also customize
this button using C.Fn-11 for use
while you’re shooting.
At the top-right corner of the Rebel XSi/450D
are two buttons that you’ll use often to
select AF points manually and to check focus
as you enlarge images during playback.
✦
AE Lock/FE Lock/Index/Reduce
button. Press this button to set
Auto Exposure (AE) Lock or Flash
Exposure (FE) Lock when the
built-in flash is raised, to display
multiple images as an index during
image playback, or to reduce the
size of an enlarged image during
image playback.
