Hi, just wanted to add to all the great comments and help and that is to ask the couple getting married what groups they would like. As this is not always
the same for everyone, having had the experience to get everyone involved
but not in groups!.
Digital is great and forgiving, try a couple of test shots before the real stuff gets going just to make sure you are not over exposing or have the wrong
resolution pictures, the camera on manual focus when you think its in auto so everyone of your shots is slightly out of focus. Once it all starts to get going it
is easy to overlook these important details. Know your gear!!!!! as you wont have time to look through a manual when an important shot needs to be taken and the images are not what you expect.
Don't want to scare you, just be well prepared and have enough time to get ready and have fun.
Regards
Glyn
