Hello, I recently brought out my Dad's old SLR and have been experimenting with different techniques. Yesterday I set up my camera on a tripod and, using a cable release, opened the shutter for a few seconds. While the picture was being taken, I had someone walk over and sit on a bench that was in the photo. My intention was to create some sort of ghosting effect of the person's movement. The problem is, I think I may have over-exposed the film by opening the shutter for so long during the day, and this may result in a bleached out/white photograph. However, this was not taken in direct/bright sunlight. Any input/advice on this type of slow-shutter-speed photography would be appreciated, as I am new to this camera.
