Set [z2: Auto Lighting Optimizer] to [Disable]. When [Low],
[Standard], or [High] is set, even if you set a decreased exposure
compensation or flash exposure compensation, the image may come
out bright (p.169).
When the image-recording quality is set to 41 or 61, the
multiple-exposure image will be recorded in 1 quality (p.218).
If you shoot at night when the background is dark, the shutter speed
automatically becomes slow (slow-sync shooting) so that both the
subject and background are properly exposed. To prevent a slow
shutter speed, under [z1: Flash control], set [Flash sync. speed in
Av mode] to [1/250-1/60sec. auto] or [1/250 sec. (fixed)] (p.236).
In shooting modes (
flash firing), the built-in flash will be raised automatically when
necessary.
In the <8: xG> and
press the shutter button halfway under low-light conditions, the built-in
flash may be raised automatically and emit the AF-assist beam.
Even though I set a decreased exposure compensation,
the image comes out bright.
The multiple-exposure image is shot in 1 quality.
When I use the <f> mode with flash,
the shutter speed becomes slow.
The built-in flash rises by itself.
