CA61E839-9051-4EF2-8739-1E333FC63215.jpeg I’ve got a line across all the photos from frame 22 on a roll of Fuji Superia 400. It was hand processed commercially and scanned by me at home.

Any ideas what it is?

Right, same as me. When you put the negative carrier in, there's a small gap at the top. Thats something to do with calibration, teeny bit of dust in that bit, whether its on the glass or the light, will result in what you've got there mate :)

Neg film + black line through several frames = scratch, hard to say when it occurred though. Dust whilst scanning will result in a spot not a black line through several frames.

Dust in the calibration area will give a line on the whole strip of negatives.

You will have to excuse me if I am being thick, but, how?
On some flat bed scanners there is, as someone already mentioned, a small open area of the film holder just before the actual place that holds the film. This is scanned each time so that any variation in the light source or the sensor across the width of the film can be allowed for. Dust in that area will appear in the adjusted density of the film scan as a line running in the same direction as the scan.

Scratch on film is easy to see so that's quickly confirmed or........

I think I understand now, so it is mapping out the pixel/s where the dust is? Thank you. It has been a long time since I used a scanner and then it was Flextight....;)

Thanks a lot for the help and the explanations. I've rescanned after cleaning the area you both mentioned and I no longer have lines!
