This is Fuji HRT, 8 years old, with a Hoya K2 yellow filter permanently fastened to the rear element of my Bausch and Lomb 12 inch lens in a Betax #4 shutter. First sheet exposed at ASA 25 and developed 5 minutes, 75 degrees in Rodinal 3ml to 10 ounce water. Results: printable, but not perfect. The second ASA 12 same developer and dilution 4 minutes, 75F. On the second, the film showed more printable sky, but a bit lacking in the shadows. More tests are needed. At this time, I believe ASA 12 and 4 1/2 minutes 75F looks like a good place. I was particularly pleased overall. I don't feel so constrained by the constant fight to win over the well-known high contrast battle in using X ray film.
