for gamma 2.2, the Bright multiplier must be 0.4545 ). The Bright multiplier is the inverse of the gamma value (i.e. In this case, the Dark multiplier is a general multiplier for the colors before they are gamma-corrected. Gamma correction - this mode applies a gamma curve to the colors.Intensity exponential - this mode is similar to the Exponential one, but it will preserve the ratio of the RGB color components and will only affect the intensity of the colors.HSV exponential - this mode is very similar to the Exponential mode, but it will preserve the color hue and saturation, instead of washing out the color towards white.This mode will not clip bright colors, but will instead saturate them. This can be useful to prevent burn-outs in very bright areas (for example around light sources etc). Exponential - this mode will saturate the colors based on their brightness.This can result in burnt out spots near bright light sources. Color components that are too bright (above 1.0 or 255) will be clipped. Linear multiply - this mode will simply multiply the final image colors based on their brightness.Type - this is the type of transformation used. Color mapping has the task of re-mapping the image values to be suitable for display purposes.

Sometimes an image can contain a higher range of colors that can't be displayed on a computer screen.

Color mapping (also called tone mapping) can be used to apply color transformations on the final image colors.
