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

Stripping literally cuts the DR in half. You also end up with a muddy looking, grainier image. Definitely a waste of time. If you have to strip, then best to use a single-sided film like Ektascan.

Ah yes, of course, there are barrel-shaped drums as well. The one I have is perfectly round though, so this approach doesn't work for me, sadly. Single-sided film is also very hard to come by here in Europe.

I have developed using hangers, but one must be very careful inserting and pulling the film out of the hangers. Really gentle agitation... I barely pull the hanger out of solution. My favourite method is still flat-bottomed tray.

Oh really? :) :)

I love how dogmatic this keep getting. "no rotary" "must strip" & etc...

Rotary is only thing I use. I have not stripped single sheet in about 2.5 years, didn't like what it gets me. I have not scratched sheet in about 3 years, i think.
I do loading into tube inside of smallish tent. Loading of holders typically - in darkened room. Using both old wooden holders and modern plastic ones.

I think it is important to just find something that works. Experimenting is pretty much only one way to get there. I had film scratched during loading and while getting it out of tubes, till i figured and got all the moves right for myself. We all humans - we all have different control over fine motor skills.

There are days i can walk with cup of water on my head. There are days i can barely walk straight and need to hold onto stuff.

Once again an amazing result Sergei, I have ordered a mod54 insert for 4x5, you have convinced me to give rotary a try!

Thanks , Andrew.

Mod54 is a bit funky. I threw mine away (no one wanted it back in Russia). I never got it to point where at least one of regular film sheets would escape or get scratched.
It was 1st revision, and honestly saying - i wouldn't recommend it to anyone.
Imho Jobo did WAY better job. But then one can make similar hack for paterson's tank from just unused 120mm spindle , i think. But i heard 2nd revision was a bit better.

Thanks Sergei, yes I have read bad things about the mod 54 for inversion, but thought rotary would be a lot more gentle on the film. I'll try it, if it causes too much angst I will return to tray, which I find relaxing anyway.

Hello SergeiR,

I am always very impressed with the work you produce using CSG Green. You mention Jobo above...do you use Expert Drums? Do you process on CPA/CPP style equipment or more manual like a roller base?

I have had recent success processing CSG Green in flat bottom trays, but that's single sheet at a time. My Expert Drum would enable me to process multiple sheets in one go. :)

thank you, Alan

Ii use both Jobo and Unidrum tanks, depending on work load and how i feel. As a result its either Jobo's CPP2 (ancient one, without lift) or Unidrum's rotary base (i don't like it bc you have to watch damn thing like a hawk, so drum won't fall off, but its far more compact space wise).
I have manual Jobo base too, and used it with 20x24 tank, but its rare. So my batch is 2-3 sheets in one go.

There is actually full description on how i deal with Xray film on my site/blog ;)

I do not own any expert drums :( I really wanted one for color work, but they are more expensive and i do have only ancient Jobo CPP, so its not like i can use it anyway)

I tried the MOD54 once with double idd film cut to 4x5. I wasn't happy with the results because the 'fingers' of the MOD54 that hold the sheets left visible impressions on the backside of the film and too far into the image area to my taste.

Hi Koraks, yes on another thread they say that the middle holders, which have a solid support, forces the soup to divert around and causes a faster flow which makes for uneven development. Was that with rotary or inversion??
