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
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 f/stops more

than normal.
