I've been shooting for years and sometimes my lab scans come back with horizontal lines in them. It's somewhat rare that I see them, but I was sad that it happened on this roll as I liked a lot of the shots. I asked one of the employees, and he was not certain. I think it might be something in the scanner or density adjustment, but can't say for sure.
The details:
- ProImage 100
- Nikon F100
- AF-S 85mm 1.8 G
- Noritsu scanner
- Processed in a rotary machine, as their mini lab is down for the moment.
I put a curve on this shot to emphasize the lines, but they were somewhat apparent. These lines look somewhat bowed, but other times they are straighter.
Can you check the negatives? Looks like bromite drag.
Wow, yeah that could absolutely be what the issue was. This video described the issue, and knowing how some film can curl in the plastic reels I can see how the denser bromide might have collected in the center of the negative during development and created this effect.

Lack of agitation is usually the cause, so who knows if they are using the rotary machine or processing manually.
