Using blue sensitive x-ray film

After spending a few days trying different techniques to getting a descent exposure on the x-ray film I finally solved it. At ISO 100, ID 11 1:1 7 minutes, stop 30 sec fix for 5 min then wash wash wash. I really like the tones, not quite black and white.. And the good thing is I have at least 80 sheets of film left and each sheet gives 4 5'4' images so lots and lots to go.  Now I have cracked the method I can come back and work with it fr a future project. I would still like to photograph the cinemas, John Maltby style. Will see if I'll have time for that before the end of May, if not, then a later date will be just as good I guess.
