*Histogram Match

Pre-Processing > *Histogram Match

Requires Companion Image

Modifies the overall contrast of the Current Image to match as closely as possible to the overall contrast of the Companion Image. Often used when you have a series of images that you want to normalize the contrast of. In this case use Memory > Load Companion Image to load the “comparison image” into the Companion Image slot. Then use Memory > Call Original Image to bring forward the original Opened Image. Then Histogram Match will adjust the contrast of the Opened Image to match that of the Companion Image (i.e., “comparison image”).
