Why be immersed into photography when you're an eye surgeon/doctor?

This is a question I am often asked by my colleagues and friends in the medical field. But here's my answer to their queries:

    When one is in a creative mood of painting or photography, the instant you visualize an object as being worth a capture by whatever medium you start to use your right brain involuntarily. The right hemisphere of the brain sub serves all visual activities and processes information in an intuitive and simultaneous way, looking first at the whole picture then the details - from matching colors, lighting, positioning the subject, arranging the elements in the set until the picture is processed into a final image or until a painting is mounted into its own frame. 
  
  Once I put on my scrub suit and go into the operating room, the left brain dominates - the hemisphere that subserves critical thinking, the analytical and sequential processing of the job at hand.


  So the reason I do both art in between my day job as a medical specialist is for me to get both the left and right hemispheres of my brain pretty much at par with each other, keeping them polished and as productive as they should be.  


   I just hope that by keeping them in tip top shape I will lessen my propensity to develop the dreaded Alzheimer's disease.


   Now for some details of the picture above, here I was trying to emulate the effects done my noted Dutch painter Rembrandt van Rijn, better known simply as Rembrandt. He mastered lighting his portrait subjects such that the highlights fall mainly on one side of the face creating shadows on the opposite side and fading into deep shadows. There persists a discernible detail in the shadows as the human figure is still cut out by a hint of background illumination, thus giving the 2 dimensional image a feeling of a 3 dimensional effect - the Chiaroscuro effect.
