Use Exposure 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.

To access the Exposure menu, use:
Batch, then select a node from the Node bin.
Timeline, then use Batch FX (See Creating Batch FX).
The Modular Keyer, then select a node from the Node bin.
This node accepts a front clip and a matte clip, and outputs a result. The matte input is used to limit the areas of the front clip that are affected by exposure and contrast changes.
To adjust the exposure, contrast, and image data type of the image for display purposes only, set the image display viewer options in the View menu or edit them gesturally in the current viewport. See Displaying Multiple Views
