That is, stand the subject in front of a blue screen and use color-to-alpha to remove all the blue. However, the filter removes too much blue -- the resulting colour is as saturated as possible, even if the original colour wasn't so saturated. I'm thinking that it would be handy if the color-to-alpha had a preview and slider that went from 0 to 1, where 0 = "do nothing" and 1 = current behaviour and 0.5 gives a result half way between that for 0 and 1. Does this seem useful? Is there a better way to do this? > just a thought. no, i can't prrogram it myself. I can program my idea if folks are interested. Tim
