I thought about Roger Hicks mentioning boredom. Before digital photography flooded the world with a billion images and there was merely film, you had to work at making a superior image (developing, enlarging, dodging, burning, printing, on and on) so not every Tom, Dick and Harry wanted to commit to the time and the learning curve, ergo fewer photographers and I felt as if I belonged to a highly skilled and somewhat elite group. Could have been an illusion. I guess I got bored looking at the flood of images (and probably disillusioned, too), and almost quit.
But I finally came around to a simple fact: There are good photographs and then there are all the rest and now that the whole world is snapping away and seeming to have great fun doing it, let it be, I thought, get over it. And I did.
I have the dry form of macular degeneration (ony 8%), so I'm probably good for a few more years. If and when I lose my sight I think I would take up the piano. You feel the keys, and in a way you hear what you feel.
