I believe that you may be missing the point I'm trying to make. Yes, we see that the "Ilford HP5 Plus" is at different positions. That is undeniable and rather obvious. The point I'm trying to make is that it may be within acceptable film manufacturing tolerances and your camera may be pushing those limits. Nobody yet has been able to address the engineering aspects of this camera-film interaction. But I can say I've seen it before when there has been an incursion and I've seen it more often when there hasn't. That's my experience whether you want to accept it or not. Your Bessa appears to frame the image low on the film; the rebates are not equally sized. The other point I'm trying to make is that .5mm isn't going to make or break yours or my photos. Some of these types of threads in which film artifacts are shown but little related data/information is presented make me think that we are starting to eat our own... why piss all over Ilford too quickly for a nit when they are one of the few remaining film manufacturers??? Ilford is a quite well-honed act, after all. I'd be shocked to hear Ilford say that this is a manufacturing problem. I do expect, however, that they may send you some film as a goodwill gesture. I eagerly await your report of their response.
