Auto Color


Like Auto Contrast, this analyzes the luminance of the image, finds the darkest and brightest colors used and stretches the color spectrum so that they become true black and true white. It then shifts the colors so that the average color is gray, based upon the gray world assumption.

Gray world normalization can be used to create color consistency between multiple sources.

Item

Description

Threshold

Determines the percentage of pixels which will become true black or true white. Higher thresholds will create a stronger effect, thus higher contrast.

Blend with Original

Mix the original source with the graded result.

Select Frame

By default the effect applies to the currently displayed frame. If the shot is changing drastically this can cause unwanted shifts in the grade. Activating Select Frame enables a specific sample frame to be chosen which will be used for the duration of the layer.
