back which lit her hair and back at the same time. thats it..
this was taken with 1 light mounted in a beauty dish which was stood slightly above her head height to camera right.
you can work out where it was positioned by the shadow direction behind her.
in this shot above i positioned my beauty dish just above her forehead. i mounted a second light on a stand which stood directly behind her to give the effect you see. nothing complicated at all, basically just 2 lights, 1 in front and 1 behind!
