This repository contains a list of custom CTL scritps plugins for the ART raw processor.
Each script can be loaded as a LUT in ART. In order to make it available automatically, it can simply be copied to the ctlscripts directory in the ART config folder (e.g. on Linux that would be $HOME/.config/ART/ctlscripts).
Note that many of the scripts depend also on the _artlib.ctl auxiliary library, so make sure to copy also that when installing.
-
colormix.ctl: mixes a user-selected RGB color with the image, using various blending modes -
density.ctl: increase saturation while also lowering luminance, emulating "film density" filters available for some video editors -
gamutcompress.ctl: gamut compression using the ACES method -
hueeq.ctl: adjust the hue, saturation or luminance of each pixel according to its hue -
lumeq.ctl: adjust the hue, saturation or luminance of each pixel according to its luminance -
odt.ctl: ART's take on tone mapping from scene to display -
posterize.ctl: simulates a posterization effect given by reducing the bit depth of the image -
sateq.ctl: adjust the hue, saturation or luminance of each pixel according to its saturation -
submix.ctl: mixes a user-selected RGB color with the image in a subtractive manner (i.e. as if the two colors were mixed like paint colors) -
tetrahsl.ctl: color warping by means of tetrahedral division of the RGB color cube, using a HSL interface -
tetrargb.ctl: tetrahedral color warping using the original RGB interface -
tinteq.ctl: add a color cast to each pixel according to its luminance -
wbchmix.ctl: white balance and RGB primaries correction
