Hi I've just recieved 3 rolls of film back i shot last week and clearly there is a problem with these two images. Anyone have any idea what the problem was/is? These are the last two images on the second roll i shot and are the only two images that show any problem, all others are fine. I also shot an identical picture to the one on the left just moments before which also has no problems. I therefore presume that the last picture has caused the problem. The camera being used is a Mamiya RB67 ProSD with a ProSD film back. I may not have had the darkslide in between these shots but cannot remember for sure. Thanks.
