Use the Exposure node to apply plausible exposure and contrast settings suitable to the image data type of an input clip. The values can be adjusted separately for each colour channel or controlled simultaneously.
The Exposure node accepts a front clip and a matte clip. The matte input is used to limit the areas of the front clip that are affected by exposure and contrast changes.
