Long Exposure Noise Reduction
Noise reduction is possible with images exposed for 1 sec. or longer.
[Auto]
For exposures of 1 sec. or longer, noise reduction is performed
automatically if noise typical of long exposures is detected. This
[Auto] setting is effective enough in most cases.
[Enable]
Noise reduction is performed for all exposures of 1 sec. or longer.
The [Enable] setting may reduce noise that cannot be detected with
the [Auto] setting.
