Histogram Scan

In: Filters/Adjustments



Very simple yet useful node that provides an intuitive way to remap the contrast and brightness of input grayscale images. Can be used to "grow" and "shrink" masks in dynamic ways.

  • Position: 0.0 - 1.0
    Similar to a brightness control, shifts the midpoint of the result. When used on a gradient input, this expands and shrinks the transition point.
    Important: a default value of 0 means the end result is always black, so try starting with 0.5!
  • Contrast: 0.0 - 1.0
    Adjusts the contrast of the result. Can be used to set the hardness of the transition.
  • Invert Position: False/True
    Inverts the final result.
