The document discusses exposure in photography and provides instructions for a photography assignment. Students are asked to take a series of photographs of an outdoor subject related to the theme of "The City" while varying the ISO setting. They should get at least 8 shots. The assignment tasks students with including contact sheets in their work, enlarging and printing selected photos with annotations, and creating a double page on a photographer who uses exposure effectively in their work. Photos from the ISO assignment are to be printed and the deadline is September 26th.
