What is B/W RGB paper and where does it say at Reed that they're using B/W
paper?  I've seen some stunning B/W, dead neutral, you'd think it was a B/W
silver print 4' x 4' Lightjet prints in the lobby of Pictopia here in
Berkeley. I sent them a grayscale image for a test and got back a green/cyan
print. I talked with them about achieving the quality they have displayed in
their lobby and apparently that requires testing, patience and balance to a
certain light source ie halogens, daylight,tungsten etc.. It can be done but
you have to work with the process and not expect your prints to be
metamerism free.
