Fujichrome 100, OM-2S, 28mm lens, 1 second at f/3.5, 1 Press 25B flashbulbs, tripod.
"This was the fourth try at getting this shot. The plan was to set the camera to manually expose for 1 second, trip the self timer, and run to get into position. Once the shutter opened, the flash slave (fellow caver Shawn Collins) would have only 1 second to fire the bulb. After numerous attempts to synchronize the events, which either resulted in the flash going off after the shutter closed, or with my falling into the water, we got the shot."
