    Re: Use of X-ray film: technical discussion with example images

    I haven't used D-76 in years but here are some suggestions.
    1..Get a red bulb or a red filter for your safelight.
    2. Check that it is pure red by bouncing the light off a CD. This acts as a prism and reflects all of the spectrum available from the light source.
    3. Dilute the developer 1+2 or 1+3 or maybe more.
    4. develop with the red light 4+ feet from the tray.
    5. Develop until the film looks severely overexposed
    6. Complete the processing as usual.
    7. this negative will NOT be the way you want it, BUT you can add or subtract development time to get a negative to print to your liking.
    8. Remember that the negative is not the goal, but the print is. Don't worry if it takes several sheets of film to get a print to your liking.
    Don't get discouraged if early experiments aren't to your liking.

    If there is any way to get Rodinal to the Philippines, that would be much better. 1:100, 6-7 minutes, 68F, have fun.

    Is that single, or double-sided?

    Corran's suggestion to try to get Rodinal is a good one. All the XRAY films I've tried over the past 11 years have given me very nice negatives... and it's way more economical than D76. Up here in Canada it's called Blazinal.

Single sided would be more desirable, as the double-sided is slightly softer, due to two exposed emulsions. I love it though, for alt printing. I have also made copy negatives with it from 35mm negatives blown up to 14x17.
    Yes I will try this and I think single sided may be more desiralbe.. 14 inch would be good for a lot of the work I do.

    Thank you very much for the tips. Yes, I can get Rodinal here. Finding out about xray film made the prospect of going larger than 4x5 possible. Hope to be sharing my first attemps soon.

    This thread is insanely huge and I read quite a bit but did not find an answer to what I am looking for.

    This a curiosity question not technical.

    There is a much larger portion of people using green sensitive film, than there is blue. I'm wondering why?

    For me, lighter looking foliage. I often shoot with a #11 (green) Wratten filter and get lighter greens.

    ...and with a yellow filter, I can darken blue skies...and cloud separation.

    Green responds to a much wider spectrum of light. Blue responds to blue and UV (there is a toe that does respond somewhat to lower wavelengths). Green starts at orange through yellow, blue and UV, and is reasonably close to old-timey orthochromatic films and plates.
