◆ HISTN

#define HISTN (1 << 11)

color transfer somewhat based on the glorious paper ‘color transfer between images’ by erik reinhard, michael ashikhmin, bruce gooch, and peter shirley, 2001. chosen because it officially cites the playboy.

workflow:

open the target image, press acquire button
right click store as preset
open image you want to transfer the color to
right click and apply the preset
