Also, how long I should develop it for in D23 at around 25 deg Celsius.

Cheers

grrreat ;)

I shot round 2 with the Fuji mammo film today and developed this evening. I'm beginning to think this stuff behaves a lot like ortho litho film--very slow with a steep curve. I shot at EI 50 and I think it could use another couple stops--maybe EI 12. I dropped the development time from 13 minutes in 1:1:100 pyrocat HD to 7 minutes and the negs look just as dense. Maybe go to 1:1:200 next or mix up some Soemarko LC-1 (continuous tone ortho litho developer). On the bright side, some of these negs should be perfect for salt prints.

Here is my first x-ray film shot:

Green X-ray film, shot @ ISO 50, f8 1/4. Developed in D23 stock for 4.5 mins @ 30C. Scanned with Epson 4990, level adjustment & spot healing PS. Not Stripped.

Please comment and what is this HX in the film, something like a watermark of the film brand, but why would they do that. Please check the following points:

1. Is the film ok, I mean not fogged, just want to make sure as i cut it in iPad App safelight+
2. Exposure is ISO 50 setting ok
3. Development

Hi Raffay,

Looking good, nice image and your subject did not move!

It is impossible for me to answer your questions, as I simply don't know.

I would make another image asap and see if HX shows again in the same place. Maybe it is an x-ray mark from a shipping inspection?

Good progress!

Thank you Randy. I have made another image will process it tomorrow.

Just noticed, if you look at the image of the film box I posted above it says HX :)

Missed that also. Still, I doubt the manufacture desired it to appear on each sheet. Still might be some sort of burn through.

You do great work, Sergei! Where did you get the film?
