I know, this may not belong in this thread but I know all of the polaroid junkies are in here a lot and I figured it would help. anyways, I have 2 old 320 polaroid land cameras and I think there is a light leak somewhere. on the picture there are 3 yellow spots and a band that streaks horizontally from the middle to the edge. the band is light yellow or brown and is about an inch or so wide. please help be?
