Looks like your camera has a light leak. Your scan seems to show clear edges and interneg spaces, so the light must be coming in the front of the camera via a leaky shutter, bellows, or the like. Go in a dark room, open the camera back, put in a flashlight and cover the back as best you can, then examine the exterior of the camera for light leaks. Or stick your eye up to the open back and shine a strong light on the outside. Your saying it's intermittent suggests a mechanical problem than occurs now and then.(posted 8661 days ago)
