    What ISO is this Xray film???

    I have a 100 sheet box of 11x14 Konica Minolta Physicians Choice PPG Xray film.

    The MFGR site says this:

    Physicians Choice Films are compatible with all major chemistries, and are designed for automatic and hand processing cycles.

    Type PPG is a high contrast, green sensitive, orthochromatic medical imaging film. Designed for 90-second processing, PPG can also be manually processed.
    I was wondering what ISO it might be. As of now I have not been able to contact anyone at the MFGR that knows what to expect from it as B&W film.

    Any info would be most helpful.

    Thanks!

    A lot of X-ray film when used for pictorial photography gets exposed at 50 to 100 ISO with good success. I know this is not specific, but X-ray film is very inexpensive, when compared to "normal" camera film, and most people test to find the ISO with their preferred developer. I am not aware of any X-ray film, from any manufacturer that will be rated in ISO numbers that you can use for making pictorial photographs. You just have to test.

    Is that ISO 50-100 only the Blue sensitive and not the Green?

    I've shot some CXS high speed blue X-ray film. I tried some sunny 16 shots @ ISO 50 that were over exposed, 100 ISO was better.

    I use "Daylight" Agfa Cronex -- the speed varies with the light conditions. I have gotten good results at 400 ASA out under the blue sky, but it drops considerable under the dense forest -- probably due to the amount of blue light available.

    I am using Ilford Universal PQ Developer...what I also use for FP4+.

    I shoot all of my x-ray film at ISO 80. Good shadow detail in the deepest areas. I think the film you have is green sensitive. Try it at 80. Like Gene said it is so cheap you can afford to test.... even in 14x17!

    This is great news! I assumed X-ray film was about as sensitive as lith film, but I'm very happy to be wrong. I'm looking forward to shooting some 10x12!

    Same here, I'm finishing the build on an 11x14 made with hardware from a Kodak camera. I didn't get any response on a request for film holders so that construction is next. Camera Bellows gave me a quote for a bellows of 240 so I'm making one for this build. If I like the format I'm going to make a folding Wista type and get a custom bellows.

    I'll shoot the 8x10 green I have at 80 and see how it works out. I'll use Pyrocat HD too.
