Old School, I need your help!

I'm scanning some negatives from 1976. What is this rainbow distortion thru the horizontal center of the photo? It looks much worse at full resolution. It doesn't appear on all the negatives. Has anyone seen anything like this?

I'm scanning with an Epson V500.

YEa, if its a gloss print, it's probably distortions/reflections from gloss to scanner glass to gloss, etc.

That is a weird one! Make sure the glass is sparkling clean and lint free. But it may be a software issue. Try reinstalling your scanner software, see it that does the trick. Or try "Vuescan"; I find it works better than the provided software from Epson.

I remember a Similar problem some one had on another list, years ago. It turned out the neg's were touching the glass, using a flatbed scanner with the plastic film holders that sat on the glass. Negs were slightly bent and touched part of the glass. I believe it was an Epson 2400 or around that vintage.,

Just a thought

Yep, to me it looks like the neg is touching scanner glass, causing newton rings.

Flatten the negatives and this should go away

Yep. Newton Rings. They go away if I scan with the emulsion side down, as the negative is now slightly curved away from the glass rather than towards it -- hence preventing the negative from touching the glass.

Learn something new every day. Thank you for the replies.
