Hello, I'm taking some head shots for a friend tomorrow and photographing people is not my strong point, so I'm looking for a little help.. Essentially, I'm trying to figure out the best set-up for me to use, with the equipment I currently have. Here's a list of everything I've got, I'm hoping someone could provide me with an idea of how to pull it all together.. lighting is a weak point for me. D200 18-55 2.8 18-200 4-5.5 70-200 2.8 SB600 2x Slave Strobes 2x 30" silver reflective umbrellas I'll be using a white backdrop. Oh, and please hold back comments such as "If you care about your friend, then tell him to find a professional head shot photographer".. I don't need those comments, thank you.
