You can change the display of an image based on the exposure and contrast settings, and the type of image data you are working with. By default, all images are displayed in RGB mode with a transformation for video images. You can apply transformations to the image to display an optimal view of logarithmic and linear images.

See Controlling Image Display using Exposure and Image Data Type.

You can also adjust the exposure and contrast settings gesturally in the image window. See Controlling Image Display Gesturally.
