Hey, Today at work I noticed that the Merge overlay will clamp your RGB values to 1.0 for some reasons I don't really get...
Overlay: Multiply if B<0>0.5 I'm trying to make my overlay operation so I can understand what is happening here. I first went with expressions, cutting all values above 0.5 and multiply and cut all below 0.5 and screen. I am doing that for R G and B. I am getting something that looks a bit like a standard overlay. Except that it looks bad, probably because there's no smoothing of 0.5 value. But there's no clamping. So instead of expressions, I giving it a shot with keyers. Now I have something pretty close to a normal overlay, without clamping, and that looks nice. So my question is, what is exactly happening in an overlay operation ? And why does it clamp my image ? It's definitely more complicated that that simple formula.... I have been playing with my keyers settings for a while now and I'm close to have the same result but there's still something missing. If anyone knows something about this I'd love to understand what's really happening ! John
