I made my second CTL script, named “Relative Color Filter for WB and primaries correction”. It operates as front-end color filter for Alberto’s WB and primaries correction CTL script. ART has already local editing color filter based on hue value or ΔE in RGB. But this script operates in the other way based on relative RGB value. It is basically same with my previous CTL script , “Relative Color Area Correction”.
It contains 2 scripts, relcolfilter_wb.ctl and _wbchmix.ctl. Former is main script of this filter and latter is same as Alberto’s wbchmix.ctl except ART_main being disabled. And relcolfilter_wb.ctl needs _wbchmix.ctl and _artlib.ctl in same directory for operating.
CTL scripts cannot control ART’s local editing mask function, but this CTL script emulate local editing mask in ART.
How to use:
You may download this tool from above link, and copy them in your ART’s ctlscripts directory. You can select this tool from color / tone correction.
And you can see following dialog.
Select the target color, and check “Show target area” on. Then move the pivot, skew, strength slider for adjusting editing area. If you check “Apply uniform strength” on, editing effect will be same in target area.
After deciding editing area, check “Show target area” off, and you use other sliders for color editing.
Color editing effect of this tool is softer and smoother than the effect of “Relative Color Area Collection” tool.
In following image, grass and tree green is too bluish, and I would like to change green area to more yellowish.
First, select target color green, and check “Show target area” on.
But editable area is too narrow, so with skew and pivot slider make the area broader.
And to exclude some areas, use local editing mask in ART.
After deciding editing area, check “Show target area” off, and use other sliders for color editing.
