I've been going through the paces testing my new Linhof Techno, which I'm using with a Horseman 6x7 film back. I absolutely love the camera and lenses but am wondering if I'm experiencing a film flatness problem...
I'm just not sure if I'm imagining it or not... On several occasions I've shot several frames of the same image at the same settings (usually f11, 1/125th, same focus exact point) and the second image is soft, seeming to be worst in the middle of the frame. I've not used an interchangeable 120 film back extensively before, having used mostly a Mamiya 7II setup for ten years, but I wonder if this is something people have heard of? It's not a big issue if I bracket but some of you have advise on how to avoid it if it is in fact a known issue – an internet search brings up some forum threads but nothing really definitive. Are some backs or film emulsions better / worse than others in this regard? Just thought I might ask peoples opinion to help with the learning process along!
The long and short of it is that I am very much looking forward to getting a digital back to round out the kit!
