Inspired by the image appearing here, Id like to try some work with litho film. It looks like ultrafineonline.com sells Ortho Litho -- 25 sheets of 8 x 10 for about $22. I might like to try it in a pinhole camera. But as I understand that litho film is very slow for such applications, Im thinking of using it in a large format camera that I built that uses an improvised lens to expose paper negatives. My questions are basic, but Im having trouble finding good answers. How is this stuff packaged? What does it look like out of the box? Is it rigid like paper, or thinner and flimsier? Is there a paper backing? And in terms of using it in a homemade camera (think cigar box), can I mount it just like I do my paper emulsion side out and a bit of masking tape to hold it flat against the back? My understanding is that it can be developed under an amber safelight and in the same chemicals I use for my Ilford RC paper for me that would be Ilford PQ and Rapid Fixer. My stop is vinegar and water. Thank you.
