There keeps being these light leak lines on the top of the frame from my Hasselblad 500 C/M and they seem to be getting worse. The first images are the most recent. The cloud one is rotated 90 degrees. It only happens in brighter scenes. I am utterly confused and do not have the expertise to know what's happening. Please help.
