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

[Fr. Mark]

Mammography film also has an anti-halation layer, which can be helpful, too. I vote for pyrocat-hd: it is helpful for non-silver UV contact printing. Light at the start or the end of the day or "warm" interior lights require more exposure, often much more b/c there's less of the UV/Blue (and maybe green it depends on the film) in the light. I've been without a darkroom for a long time. I need to get back to it.

Great summary Tim,
I just want to add two hints based on my personal experience:
- Pre-processed blank sheets of film may be used on the bottom of regular trays to avoid scrathes, in place of glass or plexiglas.
- Considering the high cost of Metol and D76 in Europe, I use HC110 with good results. This are my personal times:
1+39, 4' at 20°C, tray processing, continuos agitation, film exposed at 25 / 16 iso.
1+63, 7' at 20°C (take into account that higher diluition will run-out faster, make your calculations on the residual strenght based on the amount of the solution when processing multiple sheets with it).

HRU Fixing Step Dental Clips 1 by Nokton48, on Flickr

I've decided to use these Dental Clips I bought on Ebay, to hold down two sheets in the Cesco flat bottomed trays, and keep them off the bottom, and keeping them from moving around (which scratches!) Here two sheets are in the TD4 Fix. The 8x10 Cesco Flat Bottomed Trays are inexpensive and available from B&H

HRU Wash Step Dental Clips 2 by Nokton48, on Flickr

Here the two sheets are moving into the wash tray. This has caused a lot of grief, if a sheet touches ANYTHING it is scratched with HRU. The sheets are well distanced, off the bottom, and can get a decent wash without getting scratched. XRAY clips are available on Ebay.

HRU Dry Step Dental Clips 3 by Nokton48, on Flickr

When I go to the dry step, I move both clips to opposite ends. So the water can drain off properly. I have made many runs this way, with only one scratch (my fault). Getting perfect sheets with HRU no defects is not an easy matter. So far I can see no reason to not continue tray processing in this way

I have used dental clips for 30-40 years. They are hard to beat. When used during development I place one on each corner. My source has always been dentists who are moving to digital x-rays, thus free.
