I would like to make 35 mm B&W inter-positives for making enlarged negatives for Alt processes. I would like to try Gum Printing. Tried it in college more years ago than I care to mention. I have seen the gum printing kits from the Formulary and am in the process of scaring up a suitable uv light source. I think that Ultrafine is the source for graphic arts film. I have an old but still functioning Bowens Illumitran so I can easily make copy positives. I am trying to avoid making same size graphic arts film positives then making negs for printing. My questions are: 1) What would be the best film to use to make inter-positives and how would you develop this film? I would like to use a film that I can purchase in bulk if at all possible. 2) Am I way off base in this way of making negatives for Alt Processing? After well over a decade of devoting my work to 4x5 and Medium format, mostly color, I have picked up my 35mm Nikon again to explore some miniature format B&W ;-) I would like to use the images that I capture in 35 to be used for some of my Alt process work. And to think that I almost had a fire sale on all my old MF Nikon equipment. Film that I have right now...APX 400, TMAX 400, HP5+, APX 100, Kentmere 400. Developers that I would like to use and have on hand...XTOL, Ilford DDX and Ilfosol 3, Pyro Cat HD and MC, HC110 I am looking at two types of Inter-positives one fairly high in contrast and the other rather full in tones and lower in contrast. I guess I am trying not to reinvent the wheel and would appreciate any advise or a good place to look on the web or in print for information on Alt Printing the analog way.
