One of the FB groups I belong to is for Self Portraiture and regularly runs themes, this one being Shadows. I had this in mind from the start, wetting down my hair and shooting it with one light.

Shot on Canon 5D Mark III, iwht the EF24-105 f/4L lens, using one Paul C. Buff Alienbee strobe. 1/200 at f/8.0, ISO 100, at 98mm.
