Asiva, I looked at your web site. The software looks inviting. I want to see more! Nice job on your artistic renderings too.
Doug, good job on separating out the color. I would suggest tweaking it a bit away from green/red toward blue/yellow, though, with hue-saturation...should come out just right!
Jak, thanks for the tip on adjusting in lab mode...great for these bad channel pics. I went a bit beyond what you did and corrected the resultant pink by layering, hue/sat, and modes...wish I hadn't closed the PSD file because I lost the steps before I could write them down. One thing I know I did was to use hue/sat on the lab corrected version to get more yellow and saturation, then go to noise-->median to blur the blotchy coloring a bit then layer it over the red channel and set to color. Other color tweaking steps followed. Another thing I recall is that I selected the forehead, nose, and shoulder areas from the original, which were washed out too much on the new version, then put them on a low opacity layer above and erased away the edges with a big fuzzy eraser to blend them in.
Of course, you would want to tweak this with color mode brush on the face and hair, etc. But it's fun to try to correct color as much as possible without going to a manual method, isn't it?
