Digital BW, The Print

Richard,

The BW (Bright White) versions tend to be more popular.  I'd guess the
"natural" (non-OBA) papers are mostly in demand for fine art or other uses
where rag would have been traditionally preferred.  I suspect the alpha
cellulose papers have been limited in the fine art world due to wood-based
paper gaining a bad reputation in the past. 

>Is there a natural one out there?

Yes, but none that I am aware of and would recommend.

I'm now using PA MatteBW and printing down the brightener selectively.
