Hi, I have recently been asked to do a family portrait for one of my co-workers. He wants to include his parents, sibling, and children for a total of 11 people. I have not done a group portrait yet and I'm a little bit nervous about getting everyone posed and mostly concerned about lighting. The plan is for an outdoor shot which is ok (mid April in western North Carolina is beautiful) , but I don't think that I have a viable option to light the shot if natural light is not cooperating (I only have a single 36" octagon softbox and a FL-36r). My other concern is that the two lenses I have for my E-M5 are the 17 2.8 (soft corners) and the 45 1.8 (too long?) . Will either be suitable? I'm not getting paid, but still want to do a good job. I did newborn portraits for him and him and his wife loved them. Any advice would be great, thanks!
