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

I have a box of 14x36 x-ray film that believe it or not I bought to use for carbon transfer tissue! For some reason I went brain dead in exposing and developing my last few batches of 14x17 film. I set up a still life yesterday and made some development changes and got things sorted out. I find that with the 14x17 one needs to be very careful with exposure. Especially when it comes to reciprocity. I frequently work with very long exposures in the dark forest and long exposures are tough to nail down.

Tri Tran, an amazing glow you've created here.

Thanks Tom, the lens created .My first though to post this one in abstract :)

Tri, very nice. This shows what the film can do in the hands of a wonderful photographer. Love the look!

Has anybody tried MRI film?

BioFlex MRI Film 8x10" 100/bx for $215. "One Sided for radioisotope and chemiluminescent imaging where bands are tightly packed."

Here's my new print.

Jim,

Do you have some information on reciprocity? A starting point for green laditude? Is it simular to a conventional film?

Thanks,

Jon
