Hey guys...I'm going to be shooting a 70 kid swim team in a couple of weeks. Because they are wanting this to take place before a meet, I'll be doing the photos outside around 2pm. Suggestions for aperture and such? I'll be using my Nikon D90 and my 35mm f/1.8. I'm thinking f/16 or f/18, as I want to make sure I'm not going to be missing any detail in the faces for such a large team. They will probably be in five or six rows. This will be my first attempt at such a large group. Suggestions are greatly appreciated!!!
