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

No, because then the projected image would be blurry. The anti-newton glass goes on top, as established in our earlier conversation about this. It's just that the rough side should be in contact with the negative, not the smooth side.

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?
