Chicago has a remarkable collection of swimming pools and historic field houses throughout the city. I discovered the Hamlin Park Pool when I moved into a north side neighborhood near the park, first as a dedicated swimmer and only later as a photographer. This was my first venture into documentary style, street photography. The Hamlin Park Pool taught me how to appreciate a situation where the light, the people and the environment itself was beyond my control. The studio is about building pictures through slow careful accumulation of detail but this kind of picture-making was about responding to the flow of energy among the children, anticipating where it might next become visible- and being ready when it did. The subject of water, girlhood and spontaneous play that I discovered in this project continues to preoccupy me; it can be seen throughout all my subsequent work.
