Keep doing that until you like the composition.
Ideally, he should have a good camera that allows you to zoom in and out. Direct the photographer to stand front and center, far enough away so he can get them all in the shot. Make sure you direct them to stand in a straight line, so they are side by side.
Decide who you want in the photo and have them walk back a few steps farther than the place you want them to stand for the picture Use the 'Go Here' command for each of them to do this. This is important, because with autonomy on, trying to keep several Sims in the same place is a little like herding cats. You can do it without a tripod or markers, but it can require you to reposition people a few times and to take a few shots before you get a great photo. I've always played around with group shots, trying to get them to work.
