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

Dirk, that's an excellent result - and to know that this is an initial attempt, that's really impressive! How did you agitate?

Andrew, how much developer solution do you use and how large is your tray for 8x10? I currently use 200ml in a 11x15" tray, which seems to be just about the minimum. I'm quite curious how you manage to get even development with intermittent agitation!

For stand/semi-stand, I don't use trays. Instead, I use hanger and tank. Standard development is in trays. 500ml of working solution (Pyrocat-HD) in a flat-bottomed, 8x10 tray. Agitation is one tray lift, north/south, east/west, every 30 seconds. I have also extended this to every minute.

Not a big fan of Kodak Ektalure B/RA, but it seems to work okay here. It was mainly an experiment to see how well it would handle semi-stand development. Scan.

Love the quietness in this image, Andrew. After playing with it a bit, I realized that I prefer to view it at 5x8 from the bottom. Yeah, good thing we all are not driving a Pinto, eh ?

My friend had a Pinto in high school in '78. I stopped riding in it when I heard about it being a bomb on 4 wheels.

Love it Andrew, quiet solitude.

Great picture, Luke. How do you process?

[Luke79]

Thank you guys ,

it was processed in a big tube , with rodinal 1:150 , constant rotation , 6 min , 20*

I just shot my first X-rays this weekend and the negatives came out very dense and hard to scan.
The details looks properly exposed, mayby something went wrong when I developed them?

I used CEA green X-ray film and tray developed in 1:100 R09 for 12 minutes.
Any advice?

That development regime will yield quite dense negatives. They should be about right for Van Dyke.

...very dense and hard to scan...The details looks properly exposed...

I am confused by your description of the processed negatives. Do you think you over exposed, over developed, or both? Can you share the lighting conditions, the ISO you used?
Personally, I shoot CSX Green @ ISO 50 and process in Rodinal 1:200 for 6 minutes (in trays). Not sure how that compares to your ISO and developer.
