Digital BW, The Print

It's not worth it to me to protect a print that's been reduced in 
quality, even, or especially, if that reduction was from the protection 
process, itself.  The unprotected prints must just be treated 
carefully.  If there's a protective product that retains both the dmax 
and the texture of the print/photo rag paper, though, I want to know 
about it.
