An enormous curved concrete dam wall fills the frame between two dark rock walls. Two thousand identical small square windows are set in perfect rows across the entire curved face of the dam, each lit from within. The water at the foot of the dam is flat black and empty. One person in an orange jacket stands alone on the service walkway, minute. Cool clear dusk light, the windows the only warm points. crystal-clear air, no haze, no fog, no mist, clean sharp detail edge to edge, deeply saturated natural colour, high contrast, no film grain
