"And that desire-the strong desire to take pictures-is important. It borders on a need, based on a habit: the habit of seeing. Whether working or not, photographers are looking, seeing, and thinking about what they see, a habit that is both a pleasure and a problem, for we seldom capture in a single photograph the full expression of what we see and feel. It is the hope that we might express ourselves fully-and the evidence that other photographers have done so-that keep us taking pictures."
