I read this from Sanders this morning and I wanted a little clarification - I 
could be misinterpreting the thought. I've never heard of underexposed negs 
causing Newton Rings. Am I understanding this correctly? I spent many years 
selling both high-end drum scanners (Hell Graphics / Linotype / Scitex - along 
with flatbed scanners from Iris / AGFA, etc) - and I never recall hearing 
Newton rings can be caused by underexposed negatives. Now I'm curious and just 
looking for some clarification.

Thanks.

"I am curious to hear more about your experience in scanning 
underexposed film directly on the glass.  My experience is that it
is a nightmare, because of the Newton rings caused by the bare
substrate on the glass (a problem I rarely encounter with a lot
of developed emulsion in a well-exposed negative).  How do
you avoid this problem with underexposed negatives on the glass?"---
