Hi all, I was thinking about getting into alternative, non-silver based contact printing processes. Only one problem: the biggest negative I shoot is a 6X9, and even that is out of an old Brownie (most entertaining camera I own...) So, under the kind guidance of J Brunner, (thanks Jason!), I was pointed to ortho-litho film. Frankly, I haven't the foggiest (pun?) clue on how ortho litho works, how to expose it, etc, etc. Do I test strip away for a proper exposure? Are exposures measured in seconds like paper or tenths of a second like film? Do I need an A/B lith developer or can I just use dektol? the questions go on and on, but the point is, can you kind souls give me some advice in the arena of the non-******ly enlarged negative?
