Histeq equalizes the colorspace through use of a histogram equalization algorithm – a technique for adjusting image intensities to enhance contrast. Parameters are:
- Gain:
- when set to 1, the colorspace is best effort. If the gain is set to 0, the result is the entire regression line of the color map.
- Blend:
- goes between a straight and a twisted line.
- Split output:
- diagonally shows in the compositor, the new results on the left and old on the right.
- Plot bins/lut:
- displays a plot of the result.
