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

I haven't followed every post in this thread, but I thought I'd add that I think I've found *my* fix for newton rings. So far it's worked, anyway.
I have a Durst enlarger, so that means the negative holder has glass top and bottom with blades for cropping. Before I would cut small strips of paper and tape them down to the side edges of the carrier and lay the negative on top. Sometimes (rarely) it helped. Mostly it would just minimize or move the rings to another area.
Now I lay 1 strip on top of the negative at the edge of the carrier, and close. So far it's worked in every instance.
I have no experience with the glass you all speak of, though it's been suggested to me often.

Hi,
But then the AN would be under the neg and not between the neg and light source which is were it should be if it is to be effective? No? 

I think we're back to square one :(

The only solution, new AN with the proper bevel!

Cheers,
Bogdan

Any chance the negative carrier can be installed in the enlarger the other 
way, ie. 'upside down'?   --Harry.

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?
