Trela suggests using a filter that attaches to the lens of your camera to eliminate lighting problems. Most filters are fairly inexpensive and can be purchased at a good camera store. He keeps a filter on his camera at all times to protect the lens and make his outdoor shooting a little crisper. Keep your elbows tight against your body and your feet apart for better balance. An auto-focus camera still needs to be held with a steady hand.
Film is cheap.
Always bring double the amount of film you think you will use. Take notes on the speed of the film and the camera settings so you can learn what works and what doesn't. You never know when that great photo opportunity will happen, so keep a camera with you at all times. You don't necessarily need to keep your best, high-end camera with you either. A simple automatic with a lens that zooms out with the push of a button works great in a pinch.
