papers vary depending on the paper and the light.
graded papers i have used are very slow
gaslight papers, very slow
bottled emulsions, some are slow, some were fst ( luminos was about asa 100 )
i wish i had peroxide and a box, i'd fume my paper and see what happens, since it
has been known to work with film, it seems like a good bet to work with paper.

This is an example of what I've done with X-ray film. This is Primax Mammography Film, shot w/o a filter @ 50ASA, developed in Pyrocat HD. Scanned on an Epson V700, and an approx. 100% crop of the image (try not to ay attention to dust and artifacts, nor to the aesthetics of the image, my brother is an easy/and willing/ target when testing things out)
Fuji HRT has a bluish base. Works well with alt processes like salt printing.
Pulling up an older thread, as I have begun to jump into 8x10. I don't have the funding to buy new film, so will be shooting with paper negatives for a while. But about this X-Ray film Maincoon--I thought I had studied the matter and made the determination that X-Ray film was blue-sensitive, and paper was mildly orthochromatic. But I've done so much of this internet research, I can't figure what's what any more. More discussion on the matter would be welcome.
In a way I wish they offered this in single side coated in 120. It would have to be sort of cheap to out price the Arista/ Foma stuff though.

Rollei Ortho 120 would be close. Not cheap in the US $15.49 per roll, I can buy a 100 sheet box of X-ray film for not much more!
No;most papers are around ISO3 when using a yellow filter,which I recommend to use to harness the contrast.Is there a way to shoot a paper negative at ISO 100? I know, "Use Film" - not the answer I need though...
I am working on a project where I need to use photo paper. I'm not restricting myself to commercial papers for this project (although that would be ideal).
I will consider a special order or using an emulsion, but I dont know where to start.
It has been suggested that "Ultrafine" papers are ISO 12, and some Kodak papers are higher again.
Any ideas?

how many stops of light does a yellow filter eat up ?
