Thank you all for your help. This x ray film I"m using, if that is what it is, is the film from Photo Warehouse. I have gotten better results from the x ray film than from trying to control the contrast with litho film. I have also experimented with digital negatives, but I'm thinking the printer I currently have will simply not produce enough density. The Photo Warehouse film is relatively inexpensive and produces good negatives, but it is not a variable contrast material and it is, I think, a matter of dialing in exposure and development.
The real problem is that it requires somewhat long exposure, and I"m thinking that using x ray film to enlarge original negatives made for albumen will create even longer exposure. My enlarger head is already only slightly less hot than the surface of the sun .
Is there any reason why selenium toning could not be used to increase density or contrast with x ray film?
