Make
sure
the
viewfinder's
shutter speed display is not
blinking
and
that
the
flash
charge indicator is lit, then
take the picture.
In low-light situations, the camera will set a slow shutter speed to ensure proper
background exposure. If a slow shutter speed is set, use a tripod to prevent cam
era shake and make sure the subject does not move during the exposure.
If the shutter speed blinks in the viewfinder, the background will be either overex
posed (if the X-sync shutter speed blinks) or underexposed (if 30" blinks). If this
occurs, adjust the aperture until the blinking stops.
Certain EOS cameras (EOS HT, EOS 10/1 Os, and EOS 5/A2/A2E) provide a cus
tom function (CFO) which automatically sets the shutter speed to the camera's
maximum synchronization speed (refer to chart on page 31) regardless of the
lighting conditions during aperture-priority AE flash photography.
