That Ain't Cool(scan)

[snausages]

Anyone have any idea what's going on here?

Last two scans from my Coolscan 9000 have produced this odd effect.

I'm using the MF glass carrier and ICE is on.

This is a crop from a 6x7 color neg:

What the?!

Thanks for any thoughts...

Newton's rings, I think. Does the glass carrier have an anti-reflective coating? Or do you have a glassless carrier?

Newton rings. Might need anti-Newton glass in the carrier ?

Yup, newton rings for sure.

Okay, got it, thanks guys. Starting to read about newton rings now. I've done a few hundred scans, with glass and glassless carriers, and never encountered it. Is it just an infrequent, unlucky relationship between film, glass and light or is it something more chronic that I now need to address?

Also, I'm not sure you're supposed to use ICE with the glass carrier.

Newton rings. They have add-ons to fix the problem. Just do a search.

My old Canon Canoscan 9950f would do it without fail on every neg in the second row. I bought myself an Epson V700 because I was so frustrated with it.

Same here. When large negatives would bend enough to touch the scanner glass surface (or so I thought). Ensuring the negatives are flatter helps.

These days I only do 35 and have no issues with the 5000ED.

could be that you have put the glass in the wrong way around and that's why you see the Newton rings now and haven't seen them before.

I turned the film over. No more rings. Is there any drawback to flipping the film other than having a flipped file?

Not that I know of.

By the way, Newton rings are not just a mysterious occurence that can only be witnessed in scans. When you have the negs in plastic neg sleeves you can often see many mulicolored rings that look like spilled gasoline. Those are newton rings.
