Description

This filter adjusts the darkness, gamma, and brightness levels on the luminance, red, green, and blue properties of an image..

This is very similar to the "Histogram Adjustment..." adjustment in Paint Shop Pro X. (I use this a lot, but with this FF filter, I can get all the sliders on one screen, so it's easier/faster to use.)

Note: the presets are probablty too extreme for most uses.
