Chapter 4: Light and Shadow
THROUGHOUT THIS BOOK, we are going to work exclusively with the sun, the built-in flash, and the off-camera flash—all small lights. The sun, small? Yes. Although the sun is physically huge, it’s also very far away, and thus it becomes a small light source.
Photographers call a shadow hard or soft, depending on how sharp its edge is. Nobody fails to notice the shadow in the photo to the left. Its edge is so sharply defined that it becomes an essential part of the picture. This is not simply a picture of a gourd: it is a picture of a gourd and its shadow. This hard shadow is an essential part of the composition.
