Hi,

Wonder if anyone can help?

About a year ago I acquired with an old enlarger, two roles of Photographic projection paper (Kodagraph) 1m wide by 30m long each, and one role of Ozagraph photographic projection film. I believe these were used to project drawings onto and then develop via some automatic developer process.

All roles are some 15 years out of date, but I have used some of the paper as a paper negative once which came out o.k.

However, I have now acquired a 4x5 camera and am now looking to use this film, paper as a regular source of paper/film negative. But I have no idea as to how to use this material in terms of exposures etc as it has no ISO rating as such.

So I just wondered if any one had come across this or similar material previously and had any ideas?
