AdjustBrightness - ComfyUI Built-in Node Documentation - ComfyUI

The Adjust Brightness node modifies the brightness of an input image. It works by multiplying each pixel’s value by a specified factor, then clamping the resulting values to stay within a valid range. A factor of 1.0 leaves the image unchanged, values below 1.0 make it darker, and values above 1.0 make it brighter.
