Method and calculation
Adjust exposure in photographic stops by multiplying linear-light RGB.
Inputs and settings
Photo Exposure accepts Exposure (stops) (minimum -5, maximum 5).
Worked example
Photo Exposure example — Exposure (stops): 1. Preview instructions: Select a still photo, then use Exposure (stops): 1. The result is a PNG with adjust exposure in photographic stops by multiplying linear-light RGB.
Output and limitations
One positive stop doubles scene-linear intensity; one negative stop halves it. The processor decodes sRGB before multiplication and encodes it afterward. Burned-out highlights cannot be reconstructed, so lowering exposure on already white regions does not recover texture.
