Flex marks on the neg

[LMNOP]

WHAT IS THIS?! What do you call it, and how do you fix it? I have struggled with these marks for months now, and I think its about time a real solution appears before I switch to digital forever. I Will usually just adjust the negative's position in the holder, but focus never seems to be just right.

Does anyone know what I mean?

Looks like a newton ring.

 

[Doyle Thomas]

those are called Newton rings and are very common and caused by contact between the film and glass

Presume you are scanning.... try wet mounting. It often helps...

The negative might be curling so part of it is in contact with the glass causing Newton rings. That also would account for why part of the photo is out of focus and part in-focus. What scanner are you using?

Newton rings

Scanning is such a pita I have already switched to digital forever as you say. Forever is relative to how long till I have the money for a Flextight though.

For about 10-years, I've used a trick that has eliminated Newton's rings so far. I went to the glass store and had them cut two sheets of anti-glare picture frame glass to a size that fits on my scanner. I put the slightly frosted side of the glass towards the negative - one beneath the negative and one on top. The bottom glass raises the negative to the proper height for focus, the top sheet flattens the negative. I don't use the carriers that came with my scanner.
