Friday Photo Quiz #4

First, we should pay tribute to Liz Kuball, who answered last week's quiz question about Margaret Bourke-White. She correctly identified the first Henry Luce magazine that Bourke-White shot for (Fortune). The magazine's working title prior to publication was Power.

Now for this week's question: At one point in his life, Ansel Adams thought about becoming a professional pianist. Then he saw the work of a famous photographer and decided to become one himself. Who was the photographer?
