This photo was made on film and illuminated by leaving the camera open while two cavers descended on different ropes, popping off old high powered flash bulbs at the sides of the cave. With thanks to my friends @michaelnicknichols and @salvarezphoto for showing me the way. #oldschool #allnighter To explore more of our world, follow @geosteinmetz」4月13日 8時04分
