I've never heard of a single sided blue sensitive xray film. You could use a green sensitive film and fit a blue filter on the lens. You'd have to reduce the EI by 2/3 to 1 stop, I suppose.

You could fix out some Xray film and coat it with a color blind emulsion on just one side. See Diane Ross and the lightfarm.org
I've thought about doing that. Anyone else try this already?Quote:

I have:

3. Fixer: Fixer Concentrate AGFA (G354) 5 Liters
Anyone tried this set?
Is it possible to get moderate quality image by using these set? Unfortunately, I live in a country where have access only for these stuff. If anyone tried or thinks that it is possible?!
It'll work, no doubt. I'm not familiar with that developer, so you may have to experiment a bit to get a usable development time. It's probably a rapid process developer, so maybe you need to dilute it e.g. 1+3 to get a more reasonable time. The fixer is probably usable as is; xray film tends to fix out easily. I'd just expose a couple of sheets at iso 80 in daylight and then develop the first, adjust development time to suit your taste for the next sheet, and so on.
You can also use any regular b&w developer, such as rodinal or d76 or whathaveyou.
Here is an image from a recent set up. This is an 8x10 carbon print. The Carestream single sided x-ray film was developed in Rodinal 1:60 for 12 minutes. The image is of a 110 year old Capiz window from a schoolhouse from the Philippines.
This exert was copied from another site. It was easy enough to find.
"If anyone else is looking for information I'll just post this response I got from Agfa:
G101 is a developer from our graphic department and is designed to develop line films. The recommended temperature (for lithographic films) is 35°C and the developing time should be approx. 25 seconds.
The G3231c is a microfilm developer. Standard conditions : temperature 38°C and developing time 12".
It should be possible to develop films as Tmax in G101 and G3231 but indeed the contrast will be higher and the film will be a bit more grainy.
We did never test these combinations but I recommend to make a test with a (much) lower temperature (f.e. 20°C) and a developing time of a few minutes.
hi,
for what it's worth,
couple of years late, but have been using the g3231c with technical pan at 100iso, diluted 1+63 for 6,5min @ 20dgrs. centigrade and getting pretty nice results...more testing needed, but definitely the right direction"
A couple of vintage shots.

This is a shot with Green full speed, ISO 100 I decided to develop it a little longer (10 minutes vs my usual 8) with Pyrocat HD 1:1:100 in jobo (six negatives, 600 ml). Predictably the contrast did go up quiet a bit, so will go back down to 8 next time. I dropped the contrast and increased mid tones quiet a bit in the scanning software:

re: using blue gel to change response
I've done this with chromogenic BW film. The results were a bit more subtle than true blue-only. I used a full CTB gel which has some green/yellow in the passband.
