I was in the process of shooting my Sister's family holiday pictures for their Christmas cards and of course my sister wanted my niece to model for the camera. I just recently bought a relatively cheap
background stand from Savage and some black muslin cotton sheet from Joann's Fabrics and here's a couple of the results. I might have a Gap ad in the making! Wanna pay me Gap? ;)
Both of these were taken with the black muslin with two strobes fired through two shoot through white umbrellas. One camera right and one camera left. Camera left was in a little closer.
