How to Take Group Portraits Using Your Digital SLR
Arrange the group.
The typical group shot has the tall people in the back and the short people in front. Make sure nobody’s mouth or eyes are blocked by other people in the group.
If you have a tall person in the group, have him lie on his side on the ground and the rest of the group kneel behind him. This positioning is definitely an improvement on the police-lineup type of shot.
