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

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.

Good video ! Thanks... Does glass work well to tape down the negative to? Or would there be a problem with that...

Glass is actually BETTER, I just don't have any large sheets of glass bigger than 11x14 to tape them to, but yes glass or plexiglass would be ideal (just make sure there's no grit or scratches on the surface, you don't want to scratch the GOOD emulsion side from abrasion).

I also used special newsprint paper that was unprinted just for the video example, I normally just use regular newspaper...

Go to lowe's and buy a thin piece of polycarbonate and have them cut it to sizeBleach does erode it after a time but a long time ... After all they use them in fish tanks and we used to use bleach to clean fish tanks at the old fish shop I worked at... Also it's cheap and won't break

When my darkroom is up and running this summer I'll purchase that kind of stuff, for now it's paper, thanks!

Someone posted this link on another forum and I figured I'd put it here just for general interest since quite a few of the pictures relate specifically to Kodak's x-ray film (made for Carestream) on the blue-tinted ESTAR base.

First attempt at x-ray. Fuji Super RX-N Blue, 7" x 17" with cutting to 5" x 7" for loading/shooting. Developed in Pyrocat-HD. Used a Paterson tank with constant agitation to avoid mottling of double-sided emulsion.

This was taken on my Deardorff studio using a peerless portrait lens and half speed blue xray film, excuse the poor quality of the reproduction, scanned on my wifes work printer

Thought I would post this here also ... as it's in the "Images shot on X-Ray film" category.
