Can anyone tell what these streaks are? I have developed 100+ rolls at home over the last few years and have only ever had this happen once before with some very old, very expired film. Several rolls turned out with these streaks in them in this batch. This was freash Kodak Ektar, fridge stored before and after exposure. Tetenal press kit processed with a Jobo CP-2, scanned with an Epson V500Photo flatbed scanner.

Not the best photos but they show the streaking well.
Thanks

I suspect film is touching the glass when scanning they look a bit like Newton rings. Do they show up under a magnifying glass? Try a rescan with the negatives inverted (shiny side with emulsion side) if the pattern moves or disappears then it is negative touching the glass if it stays in the same place or is visible under the magnifying glass then try cleaning the negative.

+1 on Newton rings.

Positive on the newton rings too

Thanks guys, rescanned upside down fixed the issue. Guess i need to buy some of those glass inserts..

I have heard that some framing stores will cut strips of anti-newton glass for you, if you figure out what dimensions you want.

I just always scan emulsion down. It does mean that I have to flip each image afterwards, but that's a pretty small price to pay.

Anybody know a place?
