# AdjustContrast - ComfyUI Built-in Node Documentation

> Complete documentation for the AdjustContrast node in ComfyUI. Learn its inputs, outputs, parameters and usage.

The Adjust Contrast node modifies the contrast level of an input image. It works by adjusting the difference between the light and dark areas of the image. A factor of 1.0 leaves the image unchanged, values below 1.0 reduce contrast, and values above 1.0 increase it.
