First of all, here's what I'm assuming the script does: 1. the script creates a "most saturated" version of the image and offers it to you as a layer. 2. then you adjust the intensity of the saturation effect by shifting the opacity of the layer down from 100% (unless you like the "most saturated" version and then you just keep the opacity at 100%). Step 2 is perfectly reasonable, but I see a problem with step 1. How do you generate a "most saturated" version and still make sure that you are not clipping any colours? Is the saturation process clip-proof? And if it is clip-proof... won't it be too weak if only a small insignificant portion of the image (a "hot" pixel for example) is over-saturated already? The problem with colour-clipping would be that you would loose colour *detail* (all the pixels will now have the same, maximum, saturation now) in the clipped parts, which you won't recover completely by reducing the opacity of the layer. This is why I thought the idea of a "most saturated" layer would work less-than-best in some situations. Mihai ------------------------ Yahoo!
