Slow synchronization (1st curtain)/Red-eye reduction flash
!SLOW
While using slow synchronization with flash shooting, you can also use this
function to achieve red-eye reduction. When shooting a subject against a night
scene, this function allows you to reduce the red-eye phenomenon. As the
time from emitting pre-flashes to shooting is long in 2nd curtain
synchronization, it is difficult to achieve red-eye reduction. Hence, only 1st
curtain synchronization setting is available.
Fill-in flash
#
The flash fires regardless of the light
conditions. 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).
Flash off
$
The flash does not fire.
Manual flash
This allows the built-in flash to output a fixed amount of light. To shoot with
manual flash, set the f value on the lens based on the distance to the subject.
ISO sensitivity
x Notes
• When the flash fires, the shutter speed is set to 1/180 sec. or less. When shooting
a subject against a bright background with the fill-in flash, the background may be
overexposed. In this case, use the optional FL-50 or FL-36 external flash and
shoot in the Super FP flash mode.
