Precautions in Automatic Fiash Modes
In some cases, automatic flash may
not be suited to your subject If, for
instance, your main subject is small
with a dark or distant background or
if the subject’s surroundings are
bright white with strong reflections,
automatic flash exposure may be af­
fected by a contrasting background,
causing under- or overexposure of
the subject This can be avoided by
switching to manual flash (see pp
24 ~ 26)
In delayed flash with the camera’s
self-timer, do not press the shutter
release button until the pilot lamp
glows
When the shooting distance is less
than one meter, flash distribution
may be somewhat uneven
Since it is possible for viewfinder in­
formation in the AE-1, AL-1, AV-1,
AT-1 or New F-1 to be the same in
flash photography as in normal AE
photography, be sure that the pilot
lamp is glowing before shooting
Confirmation of auto-exposure flash
is possible only when the 166A is
used with AE-1 PROGRAM in the full
autoflash mode
The auto-exposure confirmation sig­
nal tells you whether you are close
enough to your subject but not
