A friend asked me to do an informal shoot for her family. It will be two sets of parents, one with one 2yo, one with a 2yo and a baby, and a grandfather. We'll be outdoors, with a casual feel, i.e. sitting in the grass in casual clothes. I've only done one other group shoot - a family of 4 - and am a little nervous about this. I'm concerned about getting the right DOF and getting everyone in focus, assuming they won't all be standing in a straight line. If some are sitting and some are standing... where do I focus? Any tips for how to arrange them? I wish I had better questions to ask... any suggestions would be appreciated.
