This photo is built around a singular triangle, with strident pinks and blues alternating through dark bands of blue ocean and blue sky. Evening helicopter flights are almost invariably magical times and the later you leave the shot the better. This one was taken well after the sun had set and most colour had seemed to have drained away.
Taken on Asahi Pentax 6/7. 105mm lens. 100 ASA Ektachrome film. Shutter speed 125th/sec.
