Grr...

Foma 100 hand rolled onto a purpose made reloadable cassette (the plastic one)
This photo is the last one on the roll and the issue starts earlier (about half way through the roll). The first few frames were absolutely fine.
Camera is the Lomo Sprocket Rocket
Film was home developed in Rodinal. No issues getting the film onto the spiral. It was pushed to 400, so under-exposed and over developed. Again - the first few frames all came out fine.

My guess is either a light leak on the camera, or a light leak with the cassette. What I'm confused about is why the first few frames are all fine.
Any ideas?

I'm wondering what sort of shutter you've got on that camera, and if perhaps its not closing properly
 
Thanks Mads. It's the Lomo Sprocket Rocket, so it's not an advanced shutter. I think i'll have to put another roll through to find out.
 
No idea; I saw this when first posted, and came back when I saw responses. It did just cross my mind that as you were using a reloadable cassette, that implies to my mind that you loaded the cassette from bulk film, and that in this case the fogging is on the first part of the film loaded. Any chance of a light leak from the loader affecting the first few frames?

this was what crossed my mind, i'll be honest... how long had the film roll been in the reloader from filling the last reel ? if it's been a while, and the film mag is open to daylight, even the slightest light-leak could build up an issue. Strike that, I've jsut read the OP properly and seen "hand rolled"

That's the strange thing. The first few frames were fine. The whole lot was shot over 2 days. And I've just run a roll from the same batch through my RB67 and it's dev'd fine.

As I read it, it was the first frames that came out of the cassette that were fine; but these would be the end of the roll as it was loaded and the last frames would be from the beginning of the film, where it was attached to the spool. I did miss the "hand rolled though". Was it cut from a bulk reel, or can you still buy ready cut lengths?

It was the first frames shot that were good (the last frames to be loaded). It was from a bulk reel.
 
Which I suppose raises the question about light leaks affecting the end of the bulk reel you loaded from. Presumably it was kept in the tin it was supplied in?

N.B. I haven't loaded 35mm cassettes for over 40 years, so I'm assuming bulk film is still supplied in the same way. And I am just clutching at straws in my ignorance as to what's happened.
 
if it's coming off a roll, then the last few frames exposed in the 35mm reel pretty much HAVE to be the FIRST few frames off the "bulk reel" surely (unless you've cut a yard of film off the bulk spool in the darkroom, then attached a random end of the resulting strip to the canister spool) - whatever the mechanics of rolling the film, you take the end of the bulk roll, attach it to the little spool in the film canister, and roll it up... so - i'm still thinking that the "loose end" of the bulk reel was exposed to light somehow, prior to winding up into the 35mm canister spool.

The bulk loader is fairly straightforward and I always tend to do it in subdued light... A mystery methinks. Will put another roll through the rocket and there's a roll of BWXX sitting in my RB67 which I rolled the day after (the Foma's all gone now) so I should be able to prove camera or roller. If both come out OK, it must be the cannister...
