I recently got a 35mm color negative back from Target with blue streaks starting at around the 20th frame through the end of the roll (five or so more frames). Never had a problem there before, and honestly, I wouldn't be surprised if the error is mine. This is a cheap point-and-shoot camera (Vivitar Ultra Wide & Slim) and the streaking just happens to appear on the first beach shot of the roll. Sea air or water? Lab error? The streaking also appears over the sprockets. This frame is the worst. This is Fujifilm Superia 400. Thanks for looking.
