I was a second at an outdoor party last year and they have asked me to be the only one this year. Not much pressure last year and I got a few good shots but this year I need to do much better. They will want some crowd shots both from stage and from the back looking toward the band and of course others. I have posted one to give you an idea, it will be the same venue this year. I have a good assortment of lens and shoot a Nikon D 300. I also have 3 SB 600's that I can use off camera. I thought about mounting two of them on the sides of the stage and use triggers but not sure if it is worth the effort.
I also have a flash bracket to get the flash above the camera. I thought this might be good while walking around the concert shooting in the crowd, any thoughts?
