Next, I exit the shot while he journeys out to where the pahoehoe (smooth flow) meets the a’a (rough flow). He points a big flashlight towards the camera and walks slowly across the frame to create the glowing lava line. After finishing this one-hour exposure, we thank the location’s spiritual energy and hope that the shot will turn out.
