I need some help with a group photo. I have the Olympus E-510 with the two kit lenses; 14-42mm and the 40-150mm. My neighbors want me to take a family picture; about 14 people, outdoors. We decided to take the pictures in the early evening in a shaded area near their house. Does anyone have any tips for me? They know I don't have much experience with group pictures and they are not paying me, but I want to do a good job for them. Thanks.
