    What type of chemicals do you need to develop these? I know that Kodak Royal paper used by mini photo labs can do this if used as a negative.

    There is a fellow over at flickr in the paper negatives group who worked quite hard to get all the filters figured out for RA4 color negatives. He produced some quite beautiful results.

    Timely that this thread popped up active today. This morning I constructed a big cardboard box camera... it has 1/2 of a B&L RR lens from an old Kodak 3A that covers 8x10 easily. I used a dollar store photo frame as the "film holder" and put a piece of unicolor paper in it. I made what jnanian calls a "retina print". Opened the shutter at about 11AM this morning and closed it when we came home from turkey dinner after dark. The results are quite encouraging! It produces a very different range of tones than regular B/W enlarging paper. I just finished scanning it about an hour ago.

    It's a hybrid process so I won't post the result here, but I am very much looking forward to trying it again. I think there is not so much silver in this paper, so I don't know what would be left if I try to fix it.... I suppose I'll find out eventually.

    Ilfospeed RC digital's specs look interesting, especially its spectral sensitivity. Is this paper still available?

    I've thought if I could find some RA4 paper without backprinting that I'd try printing slides on it then contact printing the paper negatives, sort of a paper internegative that would be a lot easier to make. But while I'm not sure why, I do feel rather sure it wouldn't work well. And without paper lacking backprint it's academic anyway.

    There's a colour paper negative group on flickr (disclaimer: I started it :-D ) which has some discussion as to filtering/chems/paper etc

    unfortunately, it wouldn't work correctly. The first negative would be too sensitive to blue and the blues would be blown out regardless of the next step. Appropriate colour filtration at the lens is the best solution - I believe.

    I've been working on the filtration recently. The filters change depending on the light. Filters for Strobes are different than filters for hotlights and are different for daylight rooms etc...
    Paper choice apparently will make a difference as well, but I have not been able to confirm that yet as I only have Fuji Crystal archive.
    So far, the easiest light for me to consistently filter has been the tungsten modelling lights in my studio strobes. For these I use an 85B+cc20M + CC25Y.
    Straight out of the camera (just invert in photoshop) gives:

    Colour processing in photoshop gives images like this:
