Diving student and instructor. Student learning to dive as part of a PADI (Professional Association of Diving Instructors) open water diving course. The instructor is demonstrating a controlled ascent to the surface with his student. The divers exhale slowly while ascending at a controlled rate. This is intended to prevent lung damage due to air expansion if the diver fails to exhale during the ascent. Photographed on Egypt's Red Sea coast | |
