Shutter(s)
Shutter is used to control the light that comes into the lens. A fast shutter speed is ideal for scenes in
quick motion. A slow shutter speed is ideal for scenes that change slowly.
NOTE!
You can set a shutter speed when Exposure Mode is set to Manual or Shutter Priority .
If Slow Shutter is set to Off , the reciprocal of the shutter speed must be greater than the frame
rate.
Gain

NOTE!
You can set this parameter only when Exposure Mode is set to Manual or Gain Priority .
Slow Shutter Improves image brightness in low light conditions.
