VERTICAL BANDS ON B/W FILM

[Javi]

After develop a b/w film, there are vertical bands all along the film. In think it's due to an incorrect threading of the film in the spiral. Can anyone help me?

Welcome to APUG.

You'll need to post an example as it's near impossible to guess the nature of the problem,

Welcome to APUG as well from Bangkok!

Also could be "stress marks" caused by rewinding film the wrong way; as Ian commented, if you can post an example it will be extremely helpful to pinpoint the exact cause.

I experienced vertical banding when my shutter went out of whack. If your using a rangefinder camera with vertical traveling shutter then it may be a shutter issue.
