Flash Shooting; Auto-Flash; Red-Eye Reduction Flash; Fill-In Flash - Olympus C-3020 Zoom Reference Manual

Flash shooting

Select a flash mode appropriate to the lighting conditions and the effect you
want to achieve. You can also adjust the amount of light emitted using the
flash intensity control (P. 94).
The flash modes are as follows:

Auto-flash

Automatically fires in low-light and backlight conditions.

Red-eye reduction flash

This mode significantly reduces
the phenomenon of "red-eye"
by emitting about 10 pre-
flashes before firing the regular
flash. This mode works the
same as the auto-flash except
for the pre-flashes.
After the pre-flash, it takes about 1 second before the shutter is released,
so do not move the camera and hold it firmly.
Effectiveness may be limited if the subject is not looking directly at the
preflashes, or if the shooting range is too far. Individual physical
characteristics may also limit effectiveness.

Fill-in flash

The flash fires regardless of
available light. This mode is
useful for eliminating shadows on
the subject's face or for correcting
the color shift produced by
artificial lighting (especially when
shooting pictures against the sun
or under the fluorescent light).
Fill-in flash may not have the desired effect under excessively bright light.
