Shooting Against the Light
with
the
Backlight Control Switch
In most cases, the Canon
AE-1's Central
Emphasis Metering system will give correct
exposure readings in AE photography. How-
ever, you will occasionally encounter situ-
ations in which normal AE photography
would not provide a correct exposure reading
of the main subject. For example, when you
photograph a person standing in a room with
a
brightly
lit
window at his back, the subject
will be underexposed. In order to properly
expose the main subject, the backlight control
I
switch
is
provided. When it is held in as the
shutter
is
released, the aperture is automatical-
ly opened up by one and a half
flstops more
than normal.

Manual Override
You may occasionally wish to override
I
the camera's AE control to compensate for
unusual lighting conditions, such as in taking
:
high-key, low-key or backlit shots. This is
(
possible by disengaging the aperture ring of
I
the
FD
lens from the
"A"
mark and turning
the ring to the aperture you wish to use for
desired exposure compensation. When you
take an exposure reading either by pushing
the shutter button halfway or by using the
exposure preview switch, the meter needle
in the viewfinder will show the aperture the
camera would use on Auto.
To switch back to Auto, simply reset the
aperture ring to the
"A"
mark while pressing
the EE lock oin.
