Inspiration:

Every story has its own secret life, quite separate from its setting, and "The Sun Dog" is a story about cameras and photographs. My wife, Tabitha, became interested in photography, discovered she was good at it, and began to pursue it in a serious way, through study, experiment, and practice-practice-practice. In the course of her experiments, my wife got a Polaroid camera, a simple one accessible even to a doofus like me. I became fascinated with this camera. I had seen and used Polaroids before, of course, but I had never really thought about them much, nor had I ever looked closely at the images these cameras produce. The more I thought about them, the stranger they seemed. They are, after all, not just images but moments of time . . . and there is something so peculiar about them.

This story came almost all at once one night in the summer of 1987, but the thinking which made it possible went on for almost a year.
