Are they on the actual negative as well? Do you use squeegee? ---

You can try and see what you get when you simply invert the rgb tone curve (or each of the r, g and b tone curves). You can also share one of the negatives files for us to try. Use a sharing platform like google etc. ---

I did use a squeegee, but I cant see the marks on the negative itself. ---

Yes, I have tried that. Maybe the marks are really fine on the negative itself ๐Ÿ˜• ---

I personally think this is processing error. The lines are too straight to be caused by a squeegee. Is it on all of your scans or only one of them? If the whole strip of negatives has it on the exact same spot, then itโ€™s definitely processing error ie camera/scanner etc. ---

The marks are consistent on the set of negatives. Iโ€™ve used 2 different cameras and the same outcome. I have been scanning with transparency glass so wondering if that is being picked up with the straight line marks ๐Ÿ˜• Only one way to find out! ---

How do you scan, with a scanner? That might be an issue as well.
