T Survey

Hawkins River, Mammoth Cave, Edmondson County, Kentucky

Fujichrome 100, OM-2S, 24mm lens, 1 second at f/5.6, 1 Press 25B flashbulb, tripod.

Finding myself a few hundred meters detached from the survey group, I was alone in Mammoth Cave.  By setting the camera to manually expose for 1 second, I could simply set out in the dark and fire the bulb as the shutter clicked open."
