Newton Rings

Can anyone suggest why I am getting what appear to be Newton Rings on a print

from a scanned negative? It is not a scanning problem as I am using a glassless

carrier and the rings do not appear on screen, only when printed.

Thanks, Norman

Wild guess: could it be developing solution residue on the negative?

If you see it on print, you got it on the scan for sure..newton ring does not appear suddendly and ramdomly.

 

Maybe something rong in the development, the scan or your process emphasis the problem..

I have just looked at the neg with a magnifier, the rings are not on the neg and are not on the image on the screen but only appear when I print it. I wondered if it is to do with interference between the grain and the pixels?

Is the attached image a scan of the print?

Patrick, I looked again at the image on the screen, when I reduced the brightness up popped the rings! Obviously caused in the scanning as you suggested. It must be the rubbishy negative carrier in my Epson 4490, it just does not hold the negs flat and must have allowed the film to bow down and touch the glass. I will have to investigate a carrier that will hold it flat. I don't want to use a glass carrier as that will give even more opportunities for rings to form. Anybody any suggestions?

I've followed the suggestion of many which works for me: reverse the neg so the shiny side is

up. No more rings.

No shit? I actually stopped using the glass carrier (which was supposedly superior to the

other one) because of the massive amount of rings I was getting on this big job I was

doing......a couple of years ago.

Anthony,

I was skeptical at first, but since reversing all my negatives, both 35 and MF, I haven't seen

any rings.

Good news. Now I'll have to worry less about across the frame sharpness and getting that

film holder to stretch the film flat as possible. I take it you've not noticed any reduction in

sharpness or detail in the scans since reversing it. I'll have to try it out next time.

Is your monitor calibrated in any way? Brightness must be way off (factory default?) if you can't normally see that ring.

Anthony,

Incredibly, film flatness on my v500 does not seem to affect the focus at all. I was thinking of

buying the betterscanning.com products, like the ANR glass and carriers, but so far I can't

see a reason to.

I've reversed the film, but that still did not stop all Newton rings. Using the very thin border

frames (not sure what they're called; templates?) has solved the problem for my Nikon glass

carrier.
