Thanks Jim, I am really enjoying using this fiilm. I am not sure what to really rate it at. I only have four 8x10 holders so I did a series of 8 test shots each one stop apart. This shot was done for 8 minutes at around f/420 in cloudy light, that I metered at 1/100th at f/8 with 200 speed film. The 4 minute exposure was thin but would have been printable, and the 16 minute exposure was very dense and would have been hard to print.
Wallace, pinhole is a perfect use for this film. I might try that myself. What size pinhole are you using? You might try a slightly larger pinhole to reduce diffraction. Are you involved with the f/295 pinhole group? edit - I see you are - I'm looking at your "dreamy tree" photo over there right now.Quote:

There is no ASA or ISO cuz it's not pictorial film
So that means you are on your own- sort of
If I had a box of it, from some limited experience with brandX, I'd try EI 100-200
Then I'd use your Rodinal 1:50 in the time range as for a "real" film in that speed range. I've done my testing with Clayton F60- not a mainstream developer, but sufficiently similar to vanilla. I'll probly have to re-test, but Xray film is CHEAP so I'm not worried. The main concern has been scratching of the emulsion on the "otherside", so my next shots will be developed on hangers- hey maybe this afternoon, if my good intentions pave a road to the feed mill
Others have reported their results, but I don't recal that any were for your specifics, but certainly everyone has been very helpful to me.
Okay, Thanks for this. All now is needed, is to win bid :) As you said, itīs cheap, 100pcs 30x40cm about 22$Quote:

The image had a 3 stop range when metered and was shot in natural daylight in the shade with a silver reflector to bounce a small amount of light back on her. I shot this at ISO 100 and developed in Pyrocat-HD 1.5:1.5:100 in an 8x10 tank on hangers with standard agitation for 10 minutes. When I read the density it came in at 2.20 DR. I printed this in carbon transfer and was a test image and the crop of the 8x10 is due to some compositional issues and some areas of the tissue that pulled during development. I will print this on some Azo when I get a chance and do some comparisons. I am very happy with the green x-ray film and for me and my carbon printing it fits the bill. It does build density quickly and I used my standard red safe light to monitor development.

To the guy who was wondering about xraying the film in shipping, he shouldn't worry. my dad is a doctor and told me xray film isn't sensitive to xrays. they put rare earth sheets in front of it, which light up when xrays hit them. the light from the rare earth sheet is what exposes the film.
now i just need to buy some.
I must be "the guy": thanks!
Thanks for the photo and explanation, Jim. I've got some of this stuff also, about to try it out in a home-made camera I'm building this month. Did you bleach off the 2nd side of emulsion, or develop with the intention of keeping both emulsions?Quote:
