George Schumacher, a practicing psychiatrist, engaged in photography as a hobby from the late 50's to 1970, utilizing especially the Polaroid instant process, and he wrote this about his experience
"Often as one explores an object or subject with macroscopic or even microscopic scrutiny, the beauty and meaning seen and felt deepens to a spiritual quality. One is thus led inexorably to a more humanistic philosophy; to a better and more compassionate understanding of one's fellow man which, especially in therapy, aids in seeing and understanding more fully the "self" within. Photography thus becomes a means to a richer fulfillment in life. For me no other art medium so facilitates this integrity of seeing as photography."
