<p>[QUOTE="2manybooks, post: 3857828, member: 8267"]Yes, like most photographic printing processes, the light values are reversed with each iteration. So to get a positive print you first need a negative. If an original negative was not available, the photographer could photograph the positive image to be copied and work from that negative, but there would probably be a loss in quality each time that was done.[/QUOTE]</p><p><br /></p>
