Be there or capture the moment?

During a ceremony where you're an invited guest do you
A) Snap photos throughout?
B) Take photos before and after the ceremony? Or...
C) Don't take any because you're a guest?

Do you think it's important to
A) Follow "movie theater rules" and turn off your cell?
B) Get shots that the professional photographer might not?
C) Take a picture before congratulating the bride & groom?
D) Respect the couple's decision not to have the ceremony recorded?

If you take pictures/video at a ceremony do you
A) Ask attendees if you can post their photos online?
B) Ask parents if they have concerns about their child's image online and how they would like it handled?
C) Beat the bride & groom to the punch and have the amateur photos online before the professional photos are ready?

Everyone has a different comfort level with these concerns, obviously, but this is what I found myself mulling over at a recent wedding. Thoughts?

Congrats to Dave & Caryn!
