The Mathematics of Focusing a Camera (UMAP)

This module applies precalculus to photography. It introduces the reader to several photographic concepts, including focal length, f-stop, and depth of field. Using intermediate algebra and trigonometry, the formulas listed in the Kodak Customer Service Pamphlet are derived. The formulas are also explained in term of photography and how they can be used in that field.
