So last night I was out taking some long exposures using me Rollei and a cable release. As I was packing up and unscrewing the cable release from the camera I noticed that I had left the locking mechanism in place and began to think that none of my shots would turn out because the shutter never fired. Now I'm leaning towards thinking that the shutter did actually fire because I was able to advance the film after each shot and I heard some clicking going on as I engaged and disengaged the cable release. Normally I would notice right away that the shutter release was locked because I wouldn't be able to press the button down but I never noticed since I was using the cable release and it seemed to be engaging the shutter. Anyways, could someone shed some light on this issue? Do you think that the shutter still fired or did I freeze my a$$ off last night for nothing!
