Flash shooting
Auto-flash (No indication)
The flash fires automatically in low light or backlight conditions.
To shoot a subject with backlight, position the AF target mark over the
subject.
Red-eye reduction flash (!)
The light from the flash may make the subject's eyes appear red in the
picture. The red-eye reduction flash mode significantly reduces this
phenomenon by emitting pre-flashes before firing the regular flash. This helps
accustom the subject's eyes to the bright light and minimizes the red-eye
phenomenon.

• After the pre-flashes, it takes about 1 second before the shutter is
released. Hold the camera firmly to avoid camera movement.
Note
• Effectiveness may be limited if the subject is not looking directly at
the pre-flashes, or if the shooting range is too far. Individual physical
characteristics may also limit effectiveness.
Fill-in flash (#)
The flash fires regardless of the available light. This mode is useful for
eliminating shadows on the subject's face (such as shadows from tree
leaves), in a backlight situation, or for correcting the color shift produced by
artificial lighting (especially fluorescent light).
• The fill-in flash may not have the desired effect under excessively
bright light.
