Thanks you very much to all for your comments ! @NedL@PhotoBob : yes, I have a big bunch, and it's is very (chemicaly ?) fogged, and not lithable Now, I know I can't throw it away thanks you again. @Vincent Brady : Thanks, I was afraid, for my first print, to ruin it with the scanner light, if unfixed. But it's probably unfounded. I have however took a digishot of the setup under exposure, I liked very much the surreal purple it got ! @jnantz : Thx for looking, John
