<p>Shot off a quick roll of film today with the back of the camera taped up, and developed it in the same tank as a roll I shot last weekend before I knew about this problem. Last weekend's roll has the bands (they're even worse than before, ugh), but today's roll is perfect! Looks like it was a light leak, though it's only an n of 1. Thanks so much everyone for the help.</p>

<p>Hi Larry, thanks for the help. Do you think the issue could be solved temporarily with electrical tape around the edges of the back panel?</p>

<p>Recently shot and developed two rolls of Kentmere 400 35mm b&w film, using a Minolta X-570 SLR. There are thick black bands of various sizes cutting vertically across my negatives. They seem to happen in sets of two or three, and they seem to be randomly distributed across the film. The last time I developed film from this camera was years ago, but I never experienced this problem back then.<br> Here's a photo of a set of three (there's a very faint band to the right of the two more prominent ones):<br> <img src="http://i.stack.imgur.com/IkYtz.jpg" alt="" width="599" height="177" /><br> What is causing these bands and how can I prevent them in the future?<br> Note: both times I developed this film it was in the same tank as a friend of mine's, her film turned out perfectly without any bands, so I don't think it's a processing issue. It makes me think of a light leak - but a very unusual looking one??</p>
