Great photography is simple.
It is merely to discover, collect, arrange, create, anticipate or provoke exquisite subject matter;
and then to choose, invent, or patiently wait for that properly illuminating and perfectly enhancing light, in order to utilize the proper electronic and mechanical equipment, and the optical principles and processes, which will isolate, immobilize, and capture the combination forever in a visually meaningful and aesthetically interesting way.
It takes only a camera.
It is almost as simple as writing, which needs only pen and paper; as sculpting, which requires only chisel and mallet; or as orchestra conducting, which demands only a thin stick and an evening coat.
