I have a project that requires a watercolor illustration to merge with a colored (imaged) background, so I need the white of the illustration to drop out. This isn't a Magic Wand, Select Color Range, or any 'selection' issue like that. I neeed a sophisticated color-to-alpha plugin that will render the white (or any color, I suppose), to transparent. Needs to be Mac compatible... seen some for Windows, but can't use them.
Typically, I'm in a dealine crunch, so any help will be hugely appreciated.
Thanks.
