Which is why when my sister asked me, I told her that a pro would be much better - using high end kit and large frame film (pre-digital days).
Then she showed me the photos of her sister in law's wedding - they had paid a photographer to come up with utter dross that was far inferior to my photos.
One thing that I did not realise - I don't know if its just not an American thing or regional, but in the UK after the wedding the guests hang around the church whilst the photographer takes shots of the bride and groom, then takes group photos of the the separate families and a group shot of the friends.
Then the reception line takes place at the reception venue. However at this service, the reception line took place at the exit. I then noticed people heading to their cars to set off for the reception. I had to leave the line and chase after them to get them to hang around for photos. I was able to deal with the quizzical glances I got from them by saying "It's an English thing"
