Aperture-Priority Ae; Depth Of Field - Canon EOS 600 Instruction

Checking the depth of field
It is impossible to check depth of field when
the main switch is set at the green "0" mark.
Push the depth of field. check button and the
camera will stop-down the aperture to either the
automatically-calculated vglue (e.g. shutter-prj-
ority AE), or the one set manually (e.g. aperture-
priority AE). As you look through the viewfinder
with the button pushed in, you can see the range
of sharpness, i.e. the depth of field.
When your subject is in focus, there is a certain
area in front of it and behind it which will also be in
focus. This range of sharpness is callep "depth of
_ field".
Depth of field has the following characteristics:
1) The smaller the apertu re, the wider the depth
of field and vice versa.
2) The shorter the lens focal length is, the greater
the depth of field, provided that aperture and
shooting distance are the same.
3) The farther the shooting distance, the greater
the depth of field.
4) Depth of field is generally greater in the back-
ground than the foreground.

Underexposure - The shutter speed of 30" starts
blinking. Turn the electronic input dial and set a
larg€r aperture until 30" stops blinking.
Overexposure - The shutter speed of 2000 starts
blinking. Turn the electronic input dial and set a
smaller aperture until the shutter speed stops
blinking.
When the automatically-set shutter speed is
too slow to hand-hold, the camera-shake
warning sounds. We recommend using a tri-
pod.
Viewfinder information
In this mode, the aperture is user set and the
camera chooses correct shutter speed for the
lighting conditions.'.
Set the aperture-priority AE mode following the
steps on p. 30. The initial aperture value setting is
always 5~6 (f/5.6).
Turn the electronic input dial for the desired aper-
ture value.
