U2B0810 X-Ray Film, Ultra, Half Speed, 8" x 10", Blue Sensitive, Pack of 100

I shoot this film in 5x7 and 8x10 cameras. For me, the ISO seems to be around 200, but other photographers have different experiences. It doesn't seem to scratch as easily as Agfa, the only other x-ray film I've used. Overall, I'm quite happy with this. For 8x10s, less than a dollar a shot, for 5x7s less than 50 cents per shot. Good quality. The contrast can be high, but not as bad if you tray develop without much agitation.
