13.6 SHUTTER settings
You can select your preferred shutter unit: Shutter angle converts exposure time into
the angle of a virtual rotating mirror shutter as in film cameras.
Note: A fixed angle creates varying exposure times with varying frame rates. You can
set angles from 5.0 to 356.0 degrees.
Exposure time shows the effective sensor exposure time. With varying frame rates, it
remains identical and can be set from 1/25 to 1/8000 seconds.
Note: Maximum exposure time with a given frame rate is 1/fps, with a limit of 1/25s.
For constant exposure time over the full range of used frame rates, set it to 1/(highest
used frame rate).
