Remarks

Gamma can be used to adjust the gamma setting of the camera, if supported. There are two typical usage scenarios:

Discrete gamma video cameras will return a 0-based array of strings - Gammas, which correspond to different discrete gamma settings supported by the camera. Gamma must be set to an integer in this range. GammaMin and GammaMax must thrown an exception if this mode is used.
Adjustable gain video cameras - GammaMin and GammaMax return integers, which specify the valid range for Gamma.

The driver must default Gamma to a valid value.
