I don't know how many of you know the workout routing P90X, but I have been doing that for a while. Outside of that, the lighting on their pictures on the DVDs is amazing. It's high contrast and low key. Looks simple enough, but I can't do it. Again, I am not very experienced in creative lighting. You can see some of the images here http://www.extremebodyworkout.com/p90x-products/p90x.php
BTW I have two flashes, a 580, and Sigma 500 DG Super. I have one umbrella shoot thru/reflective.
Thanks on any help you all can give me!
