Ok, I got recruited to take the family portrait at my wife's gradparents' 60th anniversary party tonight since I am the one with the DSLR. I am feeling a bit nervous with the responsibility and would like any advice. My equipment: Canon Rebel XT (350D) Kit 18-55 f3.5-5.6 lens Old Vivitar speedlight that will flash, but no metering/control A few assorted lenses that I can use an adapter, but I feel have a bit too much distortion at the edges. Oh, and a decent tripod of course What lens/settings combo should I use? It will be a group of 10 people, most likely outdoors. Any and all help will be very much appreciated as this responsibility was bestowed upon me in short order without proper time to prepare and acquire the "right" equipment.
