My film expired
I've been shooting away with my dad's old Nikon FE , loaded with some very old and long since expired film but progress was cut short by a problem with the camera. I was getting a situation where I would press the shutter release and the camera would lock up, the viewfinder would go black suggesting the mirror was locked in the up position, the shutter may or may not have been stuck open. The camera is a mechanical/electrical hybrid, what I found was that if I set the shutter speed to M90, the mechanical option, this then allowed the mirror to return to position, the film could then be advanced to try again. This gave me a temporary workaround however the problem quickly became more frequent, then happened every shot. So I decided to stop and develop the film with whatever was on it to that point.
