The effect of a change in the brightness value varies depending on 
whether the camera is set to output 8 bits per pixel or 16 bits per pixel. 
When the camera is set for 8 bit output, increasing the brightness value 
by 4 results in an increase of 1 in the digital values output by the cam-
era. When the camera is set for 16 bit output, increasing the brightness 
value by 1 results in a increase of 1 in the digital values output by the 
camera.
