Subject: [pure-silver] newton ring problem figured out

                
A few months ago I posted a question about what was causing a weird 
white ring on my prints. It was diagnosed as a symptom of Newton Rings, 
and then the question was:  why did the Newton rings form?  I had to 
leave Houston where my darkroom is for a few months, but last weekend I 
was back in Houston and I investigated the problem further. I found 
that the glass carrier does have anti-newton glass on top, but the 
glass is beveled so that the rough side is up!

The discussion on this list made me understand that the rough side 
should be in contact with the film base side of the negative.  But, in 
my carrier, the way it is beveled forces you to put the top glass in so 
that the smooth side touches the film base.

I guess the only solution is to have the glass re-beveled so that the 
rough side is in contact with the film base side of the negative, 
correct?
