How to Take Group Portraits Using Your Digital SLR
Choose your camera settings.
Shooting in Aperture Priority mode and using a large aperture (a small f/stop number, f/3.5 to f/5.6) gives you the necessary shallow depth of field. If you’re photographing a group that’s several rows deep, switch the aperture to f/5.6 or f/6.3 so that you can keep everyone in focus. Keep the ISO range between 100 and 400 and bump it up in low-light conditions if the shutter speed is too slow. A focal-length range of 28mm to 100mm lets you capture both large and small groups. Using the image stabilization feature is optional, though you can use a tripod if you’re going to be taking multiple shots at the same location.
