I'm afraid of the hum, should I be?

There is a man who goes to the park each day with his Olympus E-M5 and blissfully sits under a beautiful oak tree with a beatific gaze. His ear is pressed to the camera and on his lap are graphs showing dynamic ranges. The curious part is that he is never seen taking pictures. A boy innocently asks him one day, "Mister how come you sit there every day and I never see you take pictures with your cameras? My daddy and his friends are always taking pictures of dogs, cats, squirrels ducks, seagulls and flowers."

The man looked up at the boy with kaleidoscope eyes. "Son, they are all searching. I found it.". His ear returned to the humming of the camera. Ommmm D Ommmm D
