When I say I want to photograph someone, what it really means is that I'd like to know them.

             Annie Leibovitz

Portraits have taken on many different forms and styles through out history,  They have been painted on walls, canvas, chiseled in stone.  There have been many different techniques from the straight forward, to the impressionist, to cubist, and the modern day "selfie".  No matter the method the goal is to portray the essence of the subject.
