im about to shoot a family in there house. Its Mother Father and 3 kids. I have 2 flashes 580ex and sunpack 383. I have a DIY BDish, softbox and 2 umbrellas that came with my impact kit from BH. Now my question is how should i set up my lights? Its gonna be taken by there tree or a fireplace. Was thinking about just using the 2 umbrellas on each side but should i use them as shoot thru or reflective. Or maybe use my softbox on one side and thats it? Thanks for your help just trying to find the best route.
