    You will get NO white whatsoever!

    B&W fix will work to fix out silver halide but will not change the image of black on black.

    Thanx PE. Might just give it try. I have some household bleach - bound to do the trick :-)

    I have cross processed RA-4 to do rough contact sheets of unmounted 35mm clour slides. It was about 1.5' in a strong first dev continuous agitation, then stop, rinse, optical re-exeposure then regular RA-4. Results are not great.

    Then yesterday was gifted a full box of Radiance III, for prints from slides. R3 chemistry - can't even find the Z-manual anywhere online. So I ran it the same as the Supra III RA-4 paper experiments, and I was almost bang on with the colurs the first test print!
    my real name, imagine that.

    Mike;

    That 16x20 in my living room is a cross processed RA4 print from an Ektachrome slide!

    It does work.

    Does Ultra Endura from 2004 work? It's yellow as lemon at this point, does that mean I can expect it to be magenta-bluish after this kind of cross-process? Can it be done in a drum? How much re-exposure is needed and to what type of artificial light?

    Is the Dmin yellow or are prints yellow with white whites? This makes a big difference.

    If it's of some importance, I develop in freshly mixed 3-part Tetenal developer, stop in diluted vinegar and bleach in Kodak RT-LU bleach fix. Absolutely white whites with brand-new paper (Kodak and Fuji), and just a slight amount of yellowish whites with old Supra III.

    That is a color balance issue and not a keeping problem.

    The paper should be OK. Supra III cannot be cross processed well.
