    Mine are frequently very dark, too, and I’ve tested, exposed and developed using BTZS.

    Never seen Kodak aka Alas, aka Carestream, Medical X-Ray Film have ISO, aka ASA marked on box or online fact sheets

    Is it blue tint, which is done to protect eyeballs, staring at X-Ray film all day?

    Try an EI of 100 0and dilute the developer 1part developer and 3 parts water at 68-70 deg F.
    I can't give you a time as I don't use D76 with this film.

    Over-exposed and over--developed. Also, the developer you are using will produce too much contrast for this film. I have used more than 500 sheets of it and never used D-76 stock. In fact, I don't use it stock with any film. diluting it,andmost developers, produces a wider range of values.

    Make sure you use 10mm Rodinol per 8X10

    NOT 1ml per 100ml in a Rotary

    Hi, I had the same problem with my first X-ray film and learnt from my mistakes.
    The unexposed parts of the film lack transparency and I resolved and in my case, it was caused by my safe light that wasn't safe and by some light coming from the bottom of the bathroom door.
    All my photos also ended up being too dark and resolved the problem by developping the film un less than 4 mn.

    After many months of struggle since I started to read this topic, I have finally taken a photo I am pleased with.
    Thank you all for sharing your work and tips here, I would have certainly given up without your contributions.


    4x5 X-ray film by T. Chabry, on Flickr

    The photo was shot with a 4x5 Newton New-View camera with a Kodak Ektar 127mm lens & Agfa G Plus X-ray film.
    The exposition was set at 100 ISO, f4.7, 1/200 s. and it was developed in Kodak HC-110 dilution B for 4 mn.
