Photo Lab Processing
 
 
 

With the Photo Lab tool, you can set the exposure, gamma, pivot, and lift of each color channel independently and in a variety of units, such as F-stops or printer lights for exposure.

The input image is first subjected to a gain adjustment, then to a gamma correction around a pivot point, and finally to a lift. Each step is optional.

Note Many of the Photo Lab tool's fields are animatable attributes—see Setting Keys Manually and Validating and Applying the Expression String.
