The unevenness of density is still there, but barely noticeable (slightly increased contrast in Ps). And yes, this is probably the best result for my film so far

An experiment to develop X-ray film using Dektol as an aggressive film developer~
~
the Film…Fujimedical green x-ray.
the Lighting… A diffused LED “shop light” off the left shoulder, ambient room light elsewhere.
the Lens & Camera…A 250mm f 2.3 Wollaston meniscus, on a 4x5 Tachihara.
the Metering… Incident light, ISO 320 (not the usual ISO 70 for Xray film).., f:11, @1/25 sec.
the Developer…A Dektol/glycin blend, @1+10 dilution, @ 3min, 65º,= extremely dense negative.
the Reducer… Kodak T-14a formula reduced the negative to totally ”clear” in 10 sec, (oops!).
~
…after rinsing the almost invisible negative I decided to continue on…
the Scanner…Epson V700…the Software: Affinity Photo 1.8.4… adjusted levels & contrast….
~
The strong grain pattern on the “soft focus” meniscus lens image is quite intriguing…
An ink-jet 8x10 test print shows promise despite my sloppy handling.
I’ll handle it more carefully next time…

Re: Use of X-ray film: technical discussion with example images
Is anybody using Carestream Industrex MX 125 industrial xray film? I believe it was originally a Kodak product.
If so, I'm interested to know what EI others are shooting at. I read somewhere that EI 100 was achievable but my limited experience has been that EI 25 is needed to get shadow detail.
I purchased the film with the intention of using it in an 8x10 pinhole camera, which has an aperture of f/375, as a faster alternative to paper negatives. However I'm finding that shooting paper negs at EI 6 (and no reciprocity failure adjustment) produces a shorter exposure time than shooting at EI 25 with a reciprocity adjustment based upon the Fomapan 100 reciprocity characteristics (which I adopted as a presumed worst case scenario).
Here's one of my better attempts.
