To support what I have said about a strong flash and bounce lighting, here is an example of a zoom mode (where normally you lose the background and darkens when using flash), where the background is well lit and the subject looks natural, without harsh flash light in his face and shadows all over.
This was done with the SB800, aimed straight up at a 14' ceiling and a Gary Fong Light Sphere (Cloud). Just a quick, random candid shot as he got his haircut.
