Film is the cheapest part of photography. The more exposures you shoot, the better photographer you become, if you pay attention to your results. You can read all you want, but you'll truly learn by doing. Don't keep your creations to yourself, though. Share your hobby with as many people as you can.
People love to look at photographs.
To sum up, don't worry about making mistakes. Just learn from them. Seek information and help from other photographers, and don't be afraid to share your work. Photography is fun as well as educational. Inc. Copyright 1995-2000.
