Lomo 400 colour in 120. Leaky edges!

Leader Jones · Jan 3, 2021

Anybody else finding that the Lomo 400 colour in 120 leaks light from the edges? It doesn't happen with Portra 400

Yep I run a lab and lomo 120 always seems to have some leaking on the rebate. Usually never affects the image though. I think they just use a inferior backing paper, it never rolls as nicely

Hey Lorenzot, That's interesting. Thanks for confirming that!

More often than not, the film and backing paper weren't kept rolled tightly. Usually operator error.

I often found the height of backing paper from lomo 120 films to be a hairline shorter than Kodak or Fuji and end up with lots of light leak.
I think the mixed use of the film spools (between Lomo vs Kodak/Fuji) also aggravates the light leak.

So I use dark bag when loading and unloading Lomo 120 films in my magazines.
But I still find light leaks so I guess it starts from the factory...

I agree the backing paper might be a mm or two less wide than other brands. I've had tiny light leaks on Lomography 400 in 120 but they don't affect the exposure area. I'm careful to load/unload in subdued light and to ensure it's tightly rolled when I give it to my local lab. Inbetween camera and lab I have a black plastic film container for 120 films.

Perhaps the Lomo backing paper doesn't have the required cross-section - thinner at the edges and thicker at the middle.
Backing paper isn't a simple thing!

That is true, but not in this case
