I've been trying printing a negative (out of Photoshop) onto drafting vellum, then oiling it for transluscence and contact printing it. That works fairly well, though the dynamic range isn't more than 3 stops and it's strangely grainy, almost like a Matisse. I've been using corn oil, which is moderately dense. I'm wondering if I might get better results with a lighter oil, or, perhaps a thinner paper (one of those Japanese bark papers?). Anyone out there doing this process who might comment?
