If you are looking for a printable negative that you can print yourself to see if the quality is worth the effort and expense, I have a quite a lot of rejects that I would be happy to send you to play with. I can find something that is proper density and in focus but rejected due to boring composition or something. 8x10 or 4x5. Let me know.
Thank you very much for your answers.
My Durst M805 works up to 6x9, i was interested in making a contact sheet and a scan from the negative.
@Dennis. That would be very nice.
