I certainly get a buzz from shooting landscapes, still lives and other subjects, but nothing comes close to the excitement and enjoyement of taking portraits.
A portrait, a moment of visual communication between the person and the photographer
A portrait, a moment of mutual complicity between the mind and my desire
A portrait, a moment of unification between the soul and my determination
A portrait, a moment of trust between the target and the voyeur
An instant of maybe 1/125 sec a moment that never will be repeat
