as the topic says, i know that the default value is 1, but is there a minimum and a maximum value for gamma?
This is old… but in case anyone needs help with this…
Gamma must be greater than 0. (default 1)
Brightness can be -1 to 1 (default 0)
Contrast must be between 0 and 1 (default 1)
There's also more issues and considerations (against our opengl binding) listed here:
