Maybe the opposable thumb has the longest history and gets a lot of credit, but the ring finger takes the cake here. Overall the hands are the most versatile tools we have. I like to press the trigger button on my camera and the list of things we do is as long as the history of mankind.
While there are a million things we can do probably 90 percent of them we do with our hands. The hands are for work what eyes are for perception. They are beautiful, expressive, powerful, gentle and firm at the same time. Too many times they go unnoticed. Without developing an obsession for hands, I am trying to follow this subject in my photos. Again if body language says anything, half of it is though hands !
