I had two rolls of AGFA RSX II, both were expired in February 2004, and if I remember correctly, then I bought them at the same time, a year ago. Since I bought them they have been stored cold, but before that I have no idea.
I used the first roll a year ago and shoot it with a Seagull 4A twin lens camera, it was the first roll of film I used it that camera, so when I saw the film and it had the spots, I wasn't sure what caused it, was it the camera, the developer – got it developed at the local lab – or was it the film. And thinking the Seagull properly isn't the best camera in the world, I first thought it was the camera that caused the problem, but I quickly dropped that idea, because it wouldn't be possible for a camera to make random spots in different colors on a film, guess if it had been the camera that made the spots, they would be in the same spot on every photo, and properly be black or white. I've since used the Seagull once more and it's actually not a bad camera.
And I've used the other film in my trusted Fuji GW690III, with the same spots in the photos, and then I knew it wasn't a camera fault.
I have googled it, and found out that it is properly fungus on the film, that's causing the effect. So keep in mind that if you spot, tiny white spots on a roll of film – here I'm talking about 35mm, because it's of course a bit hard to see on 120 roll 🙂 – they are properly going to show up as colorful spots on your finished photo. Like the ones you see below.
I haven't been able to find out, why there are two different colors. Maybe it's two different kind of fungus, or maybe it's how long the fungus spot has been there. Anyway it doesn't really matter, the fact is that the fungus leaves a mark.
This is the only time – so far – that I have see anything like this, and I shoot quite a lot of expired film.
