Mike, color correction and restoration of paintings is right up my alley and all the way into my back yard! In particular I'd like a technique/plugin/whatever which will seek out all ugly paint cracks and fill them nicely with the surrounding color. Keep me posted, please!
But a white paper -- on yellow pigments? Hmm, somehow, it has an odd ring, but I just can't put my paint-stained finger on it . . .
