In my first roll of film in a new (to me) Pentax Super Program I have a couple of photos with a lighter streak in dark areas on the bottom of the film. Here is an example. http://www.ieblog.net/wp-content/gallery/bw-roll2/06_ny-nate018thstsbwy1.jpg I am not seeing this in all of the pictures from that roll (perhaps 4 from the roll) here are a couple of additional photos from the same roll. http://www.ieblog.net/permalink/5331 Any thoughts on the cause, and repair? Would like some confirmation that it may indeed be the light seals before I start my first camera repair.
