When I tried without the you seem to imply that that kind of worked, in your next email, right? (you got the negative scanned but you see it all red) > Moreover, I couldn't manage to select a frame.

(gimp show the image as red only) cannot help on this, no clue how the images are stored etc. Will take a closer look at the negative scanning though > When I scan the slide (color positive film in a frame), the scan is > perfect. :-) Cheers, Ariel
