Digital BW, The Print

Mike,

The yellowed photorag prints have never been in any kind of 
direct light (other than normal room 100 watt). I just checked a 
box of matted prints in shrink wrap that have been dark for two 
months. They are still bright white.

Do you, or does anyone know if the optical brightener yellows 
with exposure to air? Or light? or a combination. I'd like to believe 
that the prints I've recently put under glass for a show will hold up  
for the next couple of months under normal gallery lighting.

I'm going to have to stop using the HR photorag as well because 
of this. Can anyone recommend a paper with similar white base 
and dmax? I suspect that the other Hahnemuhle papers using 
OBs will yellow as well. Too bad.

Thanks for any advice,

Jeff

doing just as you report. In all honesty, I have two boxes of 17x22 
and only used about a dozen sheets.  Also, I have a large supply 
of H. William Turner and German Etching that will take a long 
time to use up. Perhaps someone else on this list could do 
some south window tests on it. After I moved, I no longer have a 
clear facing south window.
