Had an interest in photography for a while now-my science teacher pushed me over the edge. I'm in Newfoundland, way over on the east coast of Canada, and I'm shooting with a JVC Everio hard disk camcorder-I know, I know, get a real camera. But, it's a far cry from my Kodak point-and-shoot, and I wanted the camcorder for a trip later this year. It takes pretty decent shots in more talented hands than mine and the control is enough to get me over my head. (Still, not very hard.) I also have a couple of old film cameras-pics on request. One I know is a Kodak folder of some sort and another is a Brownie Target Six-20 that I'm desperately trying to find film for. Now, so that this fits in with the beginner forum, one thing I really don't understand and wish I did is exposure time. Can someone give me a brief explanation?
