Calculations for exposure and contrast adjustments are based on the type of image that is selected in the Exposure menu.
(a) Input Data Type box
- Input Data Type box
- Select the type of image data being input to the node.Your selection determines the most suitable type of transformation to apply to the clip. The algorithm used to calculate the result is dependent on this option.
