You’re right, this is ridiculous, especially for what I was going to do with it.
Never mind. Thanks everyone.

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? :o
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.

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.)
