Guys this whole X-ray filter convo should be in the OTHER X-Ray discussion thread.
I don't usually shoot portraits (if you can call this a portrait even) but I have borrowed a friends 11x14 as I have lenses and a single holder, and was visiting my friend and decided I wanted to give it a shot, well I had no lighting and so the meter read something like 15-25 seconds (I forget) which I estimated with reciprocity to be 3 minutes long with this X-Ray film, I was pretty spot on.
Anyway 3 minute exposure f/32, 11x14 AGFA Curix in Rodinal, rotary tank.

Very nice. My film have a blue tint (I think it was the blue not the green one). How do you intent to use (show) the positive ?
I use a bleach bath bichromate 50g/sulphuric acid 50g per 1l diluted 1:9 and clearing bath 50g/l sulfite. I made the solutions for a friend desperate of the high price of Foma reversal kit and this opened my appetite to play with paper and Xray film reversal.
Funny part I see now paper as luxury/expensive compared with Xray. I tested Xray in 4x5 holders and paper in 6x7 holders (with Mamiya RB67)
Since I haven't finished the project I'll hold back on my intentions just yet but I'll share when it's done.
I applaud your reversal efforts, I'm not that advanced.
Duplicate would be a more appropriate word than enlargement.
Kodak Ektascan 8x10, it's bluer than the picture but less so than my AGFA Curix X-Ray film.
Why are you being so coy? So a contact print from an 8x10 original negative.
I experimented with enlarging a 35mm onto 8x10 x-ray film for an internegative and then contact printing that for a final negative for alt processes. The final neg was extremely soft just by eye. I postulated it was because of the double-sided emulsion so did not test further. Too much trouble to bleach the interneg and final neg. I'd rather shoot original camera negatives for alt process anyway rather than enlarge a small format negative, if I was to get back into Kallitypes.
Bleaching one side of the emulsion isn't that hard, here I made a video tutorial for it.

Stone, notice I said it was too much trouble, not too hard. I have bleached at least 100 x-ray negs. I have posted many tutorials for it - I believe I told you yourself how to do it years ago. It's not worth it to bother when lith film is better (or best, shooting original LF camera negs). If you have problems with fingerprints, wear nitrile gloves.
In terms of positives, I am planning on trying x-ray film for original positives using a bleaching/toner process. On my bucket list anyway.
