Answer
Here are a few websites with good tips that will help you get started. My advice would be to use a digital camera and have several memory cards and batteries available to switch out. You can always delete bad pictures, but you can never go back and get another picture after the moment has passed. I also recommend asking someone else to help you out - they can help round up people, make sure your batteries stay charged, etc. http://www.ultimatewedding.com/articles/get.php?action=getarticle&articleid=531 This gives you a good step by step guide: http://www.basic-digital-photography.com/beginners-guide-to-wedding-photography.html These are some more unique shots: http://www.wedpix.com/articles/008/taking-the-photographer-for-a-ride/ I also recommend looking at wedding photographer websites with your friends and getting an idea of their style. It's best to look at actual photos and not go by descriptions because their idea of casual and fun may be different than your idea of casual and fun. Talk to them ahead of time and find out if they have specific photos they want taken, and what their expectations are. Maybe even do a test shoot with them at a local park before the wedding so you can get comfortable with each other - this is a new kind of relationship for you. In other words, try to function as much like a professional photographer as you possibly can. Good luck!
