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

[Michael R]

You’re right, this is ridiculous, especially for what I was going to do with it.

Never mind. Thanks everyone.

50 sheets of this "Hyper" 5x7 is $255

Ilford Delta 100 box of 100 sheets is $233, over half the price.

Seems like a bad choice unless the intention is shooting ortho, I guess. Ilford has Ortho available in 8x10 for $155, 25 sheets, with this Hyper film at $281 for 50 sheets or $29 cheaper for the same amount (even cheaper bought in 100 sheet bulk). Just pointing it out.

I have been using X-ray film for several years and have never had a problem with the blue base. I print several alt processes including Salt, Pt/Pd, VDB, cyanotype and gum.

Color from x-ray film?

Fuji HR-U expired since 2009, "iso" 25, Caffenol-C, and my trusty 1920 Bellieni 9x12 camera.
3 combined BW pictures with blue (x2), green (x2) and yellow (x2) filter. For the yellow filter i gave 3 stops more exposure insteed of 1.



and the camera with the green and blue filters that i used.


Have fun!

No need for filters or 3 shots

Shoot X-Ray as usual, scan in color

Very interesting Chris.

Yes Jim, i think it is interesting, but i have to find some extra film holders, so i could shoot more than one set of 3 at a time...

Someone once mentioned the idea of shooting only two sheets, and with the green sensitivity in mind, using the combined exposures and some kind of "sum/difference" layer in Photoshop to virtually create the other shot. Then combine. I don't remember the details or "how-to" of it though.

An unexpected strange behavior of Fuji HR-U when developed with intermittent agitation, but i find it interesting...
9x12, Rodenstock Eurynar, yellow filter 2x (3 stops overexposure), Caffenol-C.



and something that went as expected...
(also the "usual" spots in highlights when Fuji is developed in Caffenol.)

Playing with a small magnifying glass.
9x12 Fuji x-ray Caffenol-C, something like 105mm/f3.75
