Setting the camera gain
When the exposure mode is Manual, you can set the exposure arbitrarily with the
shutter speed and camera gain. The camera gain is used to set the sensitivity of the
P-400R. When a higher value is set for the camera gain, darker objects can be
captured. However, higher sensitivity is likely to cause more noises in the image.
About adjusting the exposure and setting the aperture
The P-400R uses a combination of the shutter speed and the camera gain to
determine the exposure. The aperture is fixed to either the Resolution preferred
or the DOF preferred.
