Light seal or photo lab issue

[abone]

Hello, first post so go easy.
Just ran my first roll of film through new to me Mamiya C33 and have a pinkish vignetting on all the pictures. Photo lab store says it’s a light leak but I have new seals and I’ve run the flashlight inside the body in a dark closet test and can’t see any leakage at all.
Every pic had the same issue.
The film was ten years past its expiry date but can’t see that only affecting the sides of the film
Anything else to check?
Thanks in advance for the help!
PS moderator, if I’m in the wrong forum please redirect

How was the film stored over those ten plus years? Sealed in foil or not? Could be light or heat or something else got to it before it was loaded in the camera.

This particular roll was stored in a metal camera case, in a closet, in its original foil packaging at room temp. The rest of my expired film is in the freezer sealed in a ziplock.
That’s a good point. Perhaps I should run another roll through the camera.

Are these slides or negatives?
Can you share a backlit image of them, revealing the space between frames?
Which store?
As you appear to be a neighbour, I'm personally interested in the answer.
And welcome to Photrio.

Hi Matt,
They are negatives but I only have the scans via a drive file right now. I’ll go fetch the negatives tomorrow from the store, Kerrisdale Camera. I believe they were developed at their Van lab as the turnaround was only two days.
I just conducted another test and I can’t find any leakage, in the back or bellows.
So it’s gotta be either a development error or film quality.
Can you recommend someone in our area to process 120?

I would recommend Kerrisdale Cameras.
After them - because of their favorable pricing and good quality - I would recommend The Lab in Vancouver or, if they are still doing 120 C41 - ABC Colour (as I think they are now known).
Discoloration around the frame edges could very well be a light leak while outside the camera - the proverbial "loose roll".
My C330 also has a habit of not properly latching the back door if the operator - me! - doesn't exercise appropriate care in closing it.
It is worthwhile to wait to see the negatives before coming to any conclusions!

A 'fat roll' (where the leader hasn't been tightly wound onto the takeup spool so the whole roll ends up loosely wound and prone to leaks along the edges) was my first though but the OP says each frame is exactly the same and a fat roll usually has less leakage at the beginning. Gases from degrading foam in camera cases can fog film, but this was stored in its wrapper. FWIW converting the images to monochrome does show the vignetting is very mild once you remove the pink, and an easy fix in Photoshop. But to me it doesn't feel like a processing error, more like a a leak maybe, a scanning error,...?

Let's see the actual negatives once those become available.

In my experience, this looks like a film that was subject to excessive heat and/or cold and/or damp/humidity (and/or just poor storage).

The negatives will have a greenish tinge at the film edges and usually all the way through the film.

When we see the negatives, we will know better.
