Hmmm... 

German Etching is not a Rag paper, its a neutralized wood pulp paper. And
its 
specs list, under "special features": "optical brighteners". What makes it 
highly desirable is the very tight surface, thats really a characteristic of
it 
being a wood pulp, not a cotton rag, paper.

Silver Rag, in the other hand, is both cotton rag based, and non-whitened. 
However its one of a very special group of new papers made to resemble a 
particular type of classic photo paper. The cotton in it has been very
heavily 
calendared, and resembles a piece of cardboard more than a sheet of
watercolor paper 
(necessary for the type of coating that is used), while the front is coated 
with a rather slick, almost sticky coating to produce the deep blacks,
bright 
colors, and glossy surface its known for. Great stuff, but again, not in the

usual cotton rag paper category.

So its a bit deceptive to list these two papers for someone looking for an 
unwhitened cotton rag; they are both great papers, but neither is really in
the 
category in question. Entrada Natural, and a few other unwhitened rag
papers, 
are more the norm for that, but any of them, while looking reasonably white
on 
their own, do take on a bit of a creamy cast when placed next to a whitened 
paper such as Entrada Bright. Thats your eye adapting to the brightest white
in 
its field of vision. Remove the artificially brightened white from your
field 
of vision, and the problem goes away.
