One last thing about your tutorial vs your work on Flickr: I find that all your flickr work has a bright, airy look that wasnt really explained in the tutorial. I can pull out a pretty flat, color-correct image in Epson Scan but when I try to apply a brightening curve to it the highlights quickly clip and give an over-punchy contrasted look. Your upper midtones and highlights seem to be high and bright without clipping or bunching together, they smoothly transition into higher values, without bringing the blacks up with them. Could you please advice how to do this?
