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?

That's correct. However, I would be curious about this sheet of glass and why its beveled on the wrong side.
