Hi Tom, I don't think anybody literate in computer imaging would resave an edited jpeg back into jpeg. When I have a source image in jpeg, I save it as a lossless format for all the editing steps. It is, I hope, pretty much common knowledge that resaving jpeg is a no-no. What I see more as a hindrance to using jpeg more, is the grain increase in high iso images and disability to do major colour/exposure corrections (perhaps even local burning/dodging) in the 8bit colour space. For example, when you lighten the shadows of a jpeg much, horrible blocky artifacts (results of the way jpeg works with 8x8pixel blocks) will shop up. Ugly. Best regards, Frantisek Vlcek
