some shooting modes and settings, even
when On is selected.

on the position of the focus area or the current
scene mode, even when Auto is selected.

Shutter speed is too slow or ISO sensitivity is
high as the subject is dark. Noise can be reduced
by:
• Using flash.
• Specifying a lower ISO sensitivity setting.
When recording movies in dim lighting, the
image may become somewhat "grainy" in
appearance. This occurs when the ISO sensitivity
increases, and it does not indicate a malfunction.
• Flash is off.
• Flash window is blocked.
• Subject is beyond flash range.
• Adjust exposure compensation.
• Increase ISO sensitivity.
• Subject is backlit. Select Backlighting scene
mode or use fill flash.
Adjust exposure compensation.
