Sorry, my meter won't get me to zone 111. I used to shoot portraits for a living, and never had to adjust for "negro" skin. Exposing for the lighting and not worrying about skin tones has always rendered great results for me. I've sold Thousands of dollars worth of portraits and never failed to produce desired results for a client.
BTW: the big kid in my avatar is my hero, my son, who proudly serves us in the Navy. "SALUTE"
