Re: [Digital BW] Gelatin's two-edged sword

2010-12-30 by David Kachel

Jimbo,

I am not being critical of Mark, or even implying that something is
³expected² of him. I just wanted to know what he might happen to know on the
topic of the spray¹s effects on papers. With regard to Wilhelm¹s testing,
the apparent lack of testing of just the spray leaves us, in my opinion,
with insufficient information for trusting such a product. There seems to be
no basis for us to know that while the spray is prolonging the life of the
inks, it is also not shortening the life of the paper.

We can be fairly certain we know what to expect from the better papers
available. But once we spray something onto that paper, it is no longer a
known quantity.

One thing we know for certain is that there is a long history of
manufacturer¹s of photographic materials and ancillary materials telling us
things that are simply not true or at best, things they don¹t actually know.
We have plenty of reason to be distrustful of product claims.
