This shot is actually a crop from a (much) larger image. I got a bit carried away, and the resulting file is a 316mp monster. A forget how many shots it's stiched from, probably about 40-50. The challenge was getting shots without people in. One of the advantages of this method is that you can wait for people to walk by and get the sections of the shot they aren't in. If you take the shot in one go and there's someone in the left half od the shot then it's ruined. Using this method you just take the shots to the right, and when they've gone then you take the shots to the left.
It was a great day, a great wedding and I'm really glad this shot worked, it would be very hard to go back anddo again! :o)
