Re: Use of X-ray film: technical discussion with example images
This was the first time I’ve dealt with bellows extension and reciprocity adjustments. I used the 1:1:200 dilution for 8 minutes, with agitation for the first minute and for 5 seconds every 30 seconds. It was still pretty high contrast of course, which I’ve reduced in LR. I bet it would still print on a #2 filter or paper, but I am going to reduce time and agitation on the second negative. [This is cropped from the full negative because there were some personal items on the desk too.]

SOME Mammogram and Dental X-Ray is single sided
Industry uses SOME X-Ray custom to them
Most of that is smaller than 8X10
IF you want X-Ray, better stock up now
Any kind
Read this, even NDT is going Digi

Re: Use of X-ray film: technical discussion with example images
This was another experiment, in a couple of senses. It was taken about 5:30 p.m. EDT, so I rated the film at 50. I was also using a Symmar convertible 210/370 at 370 with just the rear element. Is there some focus shift? It was windy, but I didn’t check at the taking aperture of f32. I was in a tricky camera position, so I couldn’t hold a filter in front of the shutter.
I inadvertently placed the shadow on Zone IV, rather than III, and with the extra exposure for reciprocity correction, I was in major N- territory. So I developed in Pyrocat 12/12/2400 for 6.5 minutes, with gentle agitation the first minute, and every 30 seconds.

Re: EB/RA, I can't find any reference to this film on the Carestream site and it is also no longer listed by two European suppliers. The only single sided film I can see by is Agfa HDR-C in 18x24 cm size. I have tried the Agfa double sided and got great results so expect the single sided to be similar. Unfortunately I sold one of my two 18x24cm holders because I was reckoning on EB/RA so would be limited using this. Might buy a pack anyway.

Colleagues who love photography on X-ray films.
This small German company has everything related to X-rays and black and white films. The owner of this company is a very kind and respectful man.
I hope it's useful
Re: Use of X-ray film: technical discussion with example images
I have just been given a small selection of 4x5 x-ray film mostly all double sided.
Can this be developed like regular film in an SP-445 or Paterson Tank ?
Re: Use of X-ray film: technical discussion with example images
I ordered 2 boxes of EB/RA yesterday. Short supply maybe, but it is available. Check with your normal supplier.

I don't have a sp-445, but from what I gather, the film touches the holder on one side, or at least comes extremely close to doing so, correct? This spells disaster. I use a jobo tank that holds 6 sheets, There is lots of space between the sheets for fluid to move freely. I think the Paterson would be the better option (mod54?)
Re: Use of X-ray film: technical discussion with example images
Thanks for the tip Jim!
ZZ was out last week with none available under backorder, I was sad
Now they have it!
Just bought a case, just in case...
EB/RA is good film, I cut it down often for tiny format
