Since I've been playing around with Adox CMS 20II and POTA, I thought I'd develop some double-sided green latitude xray in POTA. I normally process with Pyrocat-HD and I wanted to see how it would look. Both sheets were developed for 8:00. The sheet on the left was in straight POTA. The one on the right, POTA 1+1. Tray developed (flat-bottomed). Slight agitation every minute. 24C. Reciprocity correction was given for both...4sec became 8sec.

Quite a difference andrew, even under the stairs, are you surprised by the results??
Yes, I was a bit surprised. I wasn't expecting the diluted version to have more contrast. Then I realised I shot them both at the same EI. For serious work, I'd probably give a third stop more exposure (or more) when using 1+1.
Now is the Time to Upgrade to Digital X-Ray
Just got this in an email

The End IS NEAR
It looks like the images taken with the X-Ray are neater than the ones taken with the LF camera. In any case, I am waiting for my request to upgrade to digital too. I have bought from them about 400 sheets.
I've got about 300 sheets of 8x10 and about 80 14x17 sheets. Once they're gone, that's likely it for me and Xray. I've got so much conventional film to use...
Hey all,
I have an 8x10 camera which I've shot a few negatives and it has been a complete failure. I think I'm doing everything right but must have missed something. I've processed 2 negatives at different times with no success. The first negative I got the faintest partial image when held up to light but pretty much unrecognizable. The film was very black and the emulsion was easily rubbed off with my finger nail. My second attempt yielded a completely black negative with no image whatsoever.
Here is my process, worked under a 6watt red safelight.
1. Exposed the negative. Each time was a different shutter speed and aperture.
2. developed in D76 1:1 for 9 minutes at 20c.
3. Stop bath tap water for 2 minutes.
4. fixed with ilford rapid fixer for 5 minutes.
5. water wash and hang dry.
Any ideas what's going wrong?
The x-ray film is fuji super HR-T 8x10 green latitude.
The sheets appear to have an almost silver tone tone to them. Once I put them in the developer they turn dark black after about 5 minutes but no image ever resolves. When I'm finished i'm left with a black negative, no image, and the emulsion is almost gooey and easy removed with a light fingernail scrape.
Oh I see you posted over here. Good! What ISO did you use? And probably D76 1+1 is too strong. Try 1+3 or weaker. Why the emulsion is gooey, says either something wrong with the film or processing. Xray film emulsion is very fragile when wet, so great care must be given...but it shouldn't be gooey.
Yup thanks.
The film just says "medium speed" but I heard it's around 100 ISO.
