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

I have noticed absolutely no diference in image quality shooting on either side so it does not matter how you put it into the holders.

Thanks for the note. In the light, one emulsion side does look a bit darker than the other, but I'll just go and shoot some sheets and see what I get.

Hello all!

As I don't have a dedicated darkroom space (small house in SoCal) it is very time consuming to set-up and tear down my bathroom darkroom to tray process my x-ray film. I have been wanting to try drum processing for a bit so I picked up a Jobo Expert Drum and a manual roller to give it a shot. I'm using Kodak Mammography film (Ektascan) so I don't need to worry about 2-sided emulsion. I have been using Rodinal/Adonal at 100:1 and getting fairly good (but not consistent) results in the trays.

Have any of you tried drum + continuous agitation to process your x-ray film?

I figure I'll try the following:

1. Rodinal 100:1 for 9 minutes at 20 degrees. 5 minute pre-soak.
2. XTOL 1:1 for 7 minutes at 20 degrees. No pre-soak.

I also have HC-110 (liquid form) and D-76 (powder form) here as possibilities. :)


Any other suggestions?

Hi Tim,

I've been using rating my single-sided Kodak B/RA at 50iso and processing for 6 minutes in Rodinal 1:100. Unicolor drums. Approx. 2 min. presoak in the drum. YMMV.

Would I believe Metol Hydroquinone ?

I've developed single-sided Kodak B/RA in BTZS tubes. Works very well. Pyrocat-HD and Obsidian Aqua. I don't bother with a presoak.

I use the Jobo 3005 expert drum, green film with emulsion on both sides and Rodinal. Develop 4(four) 8x10 sheets at a time. 4 cc of Rodinal per 8x10 sheet. That gives me 16cc of rodinal. I mix that to give me 800 cc of devloper (so 1:50). 10 cc of Rodinal per 8x10 sheet is the eecommendation but 4 cc works for me. I tried 2 cc of Rodinal per 8x10 sheet and did not like my results. Jobo recommends 800 cc of developer for 4 sheets in the 3005. I do not presoak but develop for 6 min. I like the images I get.

thats how i process mine. Not in jobo though. Dont like stripping.

SergeiR and ndg, you both get consistent, even development? How on earth does developer get to the backside evenly? I've only done rotary with BTZS tubes and I have no experience with Jobo. In the BTZS tube, the film sits very loosely, developer never gets back there to do its job evenly. Usually end up with a mottled mess.

Wondered that myself...

Also, stupid question, I've only shot 4x5 but picked up some 11x14 cheap and I'm trying understand THE BOX it's AGFA and is perforated and right there on the ripped perf is the film in a plastic black bag, I know they are light resistant but not PROOF as far as I understood?

Anyway shouldn't it come in a normal 3 part light trap box?

Seems strange?... Or is this how all ULF is?
