It's not a camera I have really ever used before - it's in very good condition having been bought by my father new in the 70's. But it's probably not been used for 20 years. I put some Impossible film in, and it seems to be giving very very long exposures - when you press the shutter release there is the initial "flop" sound, and then you wait for up to 15 seconds (although it varies) and then the second "flop" sound as, presumably, the shutter is closing - and the photograph is ejected from the camera. As a result the images are very light and blurry - with virtually no image. I'm pretty certain it is the camera at fault, not the film pack. (I had an old Polaroid pack which was doing the same thing) Does anyone know if this is a fixable fault? Anyone come accross this before? Thanks.
