Congratulations Eric! I think everyone gave some excellent advice here! I have the SB600 and it does a wonderful job. Bounce the flash whenever you can. I always try to catch people not paying attention to me, they look more natural that way. Oh yeah and don't be so nervous, I know easy for me to say huh? Just concentrate on making some awesome shots and you will do just fine. (My first wedding I was more nervous then the bride was, but that could be because she took a zanax and was drinking champagne before the wedding!!!) Deep breathes, in with the good air out with the bad! I always say! It will all turn out just fine! Brenda :)
