Line across negatives

Cakes.

I developed a roll of Neopan 1600 for the first time today and when I scanned it I noticed a few of the negatives had lines running across them.

I'm not sure if it's the cheap Aldi scanner or if I have done something wrong when I was developing.

Anybody know what happened?

Could the film be getting damaged in the camera? Running across a roller or something?

I thought that too but it didn't show up on all of the negatives

Which developer, strength and development time did you use? Mostly out of interest. Picking the right developer for the film can help with the contrast and grain size.

I shot two rolls of Kodak TMAX P3200 on Friday night, and ended up using XTOL as the developer instead of Rodinal, as there was plenty of comment about grain size with Rodinal. [I don't have any Neopan 1600 examples to hand]

This P3200 is straight from my Nikon scanner, and totally untouched.



I'm putting most of the blame on your Aldi scanner.

What kind of squeege did you use to take surplus wash off the film just before you hung it up to dry? Your (wet soft) fingers? I've found my squeege can be troublesome on occasion - I leave it in very hot water for 10 minutes so it's soft prior to taking the surplus water off the film.

Anyway, keep up the good work.

Edit to add:

I had a second thought - how did you get the film out of the cannister? Did you pop the end off, and remove the whole spool in one go, or did you pull it back out through the slot? In a darkbag, or with plenty of space around you?

I'm going to plump for cheap scanner in combination with thin, underexposed negatives. Is it a flatbed ? I've seen similar problems trying to scan and boost thin negs before scanned on a canon 8400. You end up amplifying the sensor noise to noticeable levels.

Not discounting development problems though, there are quite a few reasons why you'd end up with regular longitudinal scratches on the roll.

I used Rodinal for 8 minutes, diluted 1+50

I didn't have a squeegee so just used my fingers and used a light tight room instead of a dark bag as I didn't have one of those either


I took the film out through the slot and had plenty of room.

Can you see the scratches on the negs ? Particularly in the second case, if there are scratches there they ought to be pretty apparent. You can use a 50mm as a makeshift loupe if you don't have anything else handy. What are the negs like ? Are they mostly almost transparent ? or do they look ok density wise ?

I can see the lines of the negatives so it wasn't the scanner then.

The negs are mostly transparent too.

Might be your camera ? I've occasionally squeegeed film with my fingers (though normally I don't touch it) with no problems, I also always just feed it back out of the canister to load it on the reels, and I've never scratched film yet doing that.

You film guys! :rolleyes:

Maybe, I'll try another roll when I get some time and see what the results are like.

I'll source a squeegee too and see if it makes a difference.

Thanks for the help
