What a drag?
Now then guys and gals
On friday I developed a couple of rolls of FP4+ in the jobo, constant agitation, in DDX which is new to me as I've only use Ilfosol3 in the past. I've noticed when looking at the negs that on a few of them the densest parts have kind of drifted outside of the film margins. Now this hasn't really created any problems as such but I'm just wondering what has caused this. So far I'm thinking it could be some kind of lightleak around the corner of the film gate (seems unlikely, its a Mamiya 7 and I've never heard of this before or seen it on other rolls shot with this camera) or maybe some kind of bromide drag? From what I've read on bromide drag I'd expect to see it on stuff like stand or semi-stand developing but to be honest I thought constant rotary agitation aught to be safe from it. Any other ideas? I've included a crap iphone shot of the negs on a lightbox below, you can see this bits drifting into the rebate. |

Hi Dave,
I've also had this happen and my only conclusion is "human error" with improper loading of the film, so sometimes too loose and too slack when winding on and before closing the back. It seems very erratic/sporadic and I've noticed that when I pay dutiful attention when loading films the problem seems to solve itself. But I'm curious what others will say... It's not bromide drag in my opinion. Oh, and some people say always use the same make film spirals for the up-take spool i.e. Kodak film Kodak spool, Ilford film Ilford spool.

It's not the processing. Those negatives look very over-exposed though and it might well be light leaking under the film gate, I've seen it before.
I dsoubt it's a problem with the camera/pressure plate, rather the ange of the light striking the film itself and the high level of over-exposure of the sky. Ian |

Marty, I'm always careful to keep the film tight when loading, so if I'm doing something wrong here then I'm at a loss to think of how I could improve the situation.
I think in this particular case the roll was wound onto a Fuji reel, if that makes any odds. Ian, I think the iphone shots there is making the sky look worse than it is, increasing the contrast etc. I remember shooting these and thinking the sky was going to go pretty bright as it was one fo those bright but overcast days. I think the foreground stuff is exposed about right. These drag/leak marks are only adjacent to the densest areas of the neg though, and I can't see any drag into the image area so you could be right. I've just checked the other roll of FP4 I had in the tank at the same time and there's a couple of woefully overexposed 6x12 images on there with very dense frame edges but these show no leakage, so maybe it is indeed the camera. Bloody cheap japanese junk! |

I tend to overexpose as a matter of course and see this regularly on all formats and different makes of camera. I put it down to light possibly bleeding along the film base to outside the frame area. It usually occurs in landscape shots with a bright sky.

I agree with Bill. I get the same effect from time to time, especially with bright skies and shots which include the sun. I don't think it is a camera problem. Alex

Thanks for that guys, reassuring to hear its not just me!

I looks very much like the anti halation layer was not quite up to the job. It will affect all films with a high intensity light spot such as yours.

I've seen this effect in shots with a particularly bright sky such as those, especially on the old Kodak infra-red film which I believe had no anti-halation layer. There's no sign of a problem on the edge markings which look normal so I would wager your processing is not at fault.
