I use Ulead Photoimpact as a graphics program, which is a great program, and i love it, but people only write icon tutorials for PSP and etc. Which means I have to do alot of hunting to figure out how to translate that into PI.
So, a quick cheat sheet for stuff i keep forgetting:
"Screen" is "Inverse of Multiply"
"Exclusion" involves having three copies of the color to exclude, set at "Inverse," "Inverse," and "Difference."
Fake the "Color Burn" - Here
Personal most used layers for icons:
image - pink flood (overlay) - image (soft light %) - dark blue (inverse %) - image (soft light 99%)
