Last month I purchased 300 sheets of 5x7" Thermo Scientific CL-Xposure blue base X-Ray Film (mystery film) on eBay for a total of $30 and Monday was the day to test some out. My Wife's birthday was on Friday and she received these flowers from a family member so I decided to test out the film with the flowers and my Burke and James 5x7.
There were several goals I had in mind for this test including making sure the film was good, figuring out what the film's ISO was, trying out development of X-Ray film using glass lined trays under red safelight instead of my usual daylight tank processing and finally to try developing X-Ray film with Pyrocat HD instead of my usual Rodinal. I think I succeeded on all counts. I'm a happy camper with 299 more sheets of 5x7 to shoot.
