A general rule to stick to is to apply the assumed_gamma
right when beginning a scene. In combination with Display_Gamma
(set in the INIs), it calculates a realistic gamma for your images.
The only method of solving your problem is to either
calculate the actual effect the gamma has on the colors
(though that is beyond my skill, the mathematics for
display_gamma and assumed_gamma are found somewhere
in the docs, and you may derive the required formulaes from
there), or to change it by hand...
