❚❚ Flash Modes
The options available vary with the shooting mode.
• N (fill flash): The flash fires with every shot.
• NY (red-eye reduction): Use for portraits. The flash fires with
every shot, but before it fires, the red-eye reduction lamp lights
to help reduce "red-eye. " Not available in 4 (underwater; 5,
6) mode.
• NYp (red-eye reduction + slow sync): As for "red-eye reduction",
above, except that shutter speed slows automatically to cap-
ture background lighting at night or under low light. Use when
you want to include background lighting in portraits. Available
only in modes P and A.
• Np (fill flash + slow sync): As for "fill flash", above, except that
shutter speed slows automatically to capture background
lighting at night or under low light. Use when you want to cap-
ture both subject and background. Available only in modes P, A,
and 4 (underwater; 5, 6).
t
• Nr (rear curtain + slow sync): As for "rear-curtain sync", below,
except that shutter speed slows automatically to capture back-
ground lighting at night or under low light. Use when you want
to capture both subject and background. Available only in
modes P, A, and 4 (underwater; 5, 6).
• Nq (rear-curtain sync): The flash fires just before the shutter
closes, creating a stream of light behind moving light sources
as shown below at right. Available only in modes S and M.
• s (off): The flash does not fire. Available only when built-in
flash is raised; not available in o (night portrait) mode or when
HDR is disabled in m (backlighting) mode.
