I watched the Nat Geo channel yesterday, saw a show called "Capturing the Deep."
Couldn't believe what I saw, over and over:
-dive photographers constantly lying on coral (not sand) to get their shots
-dive photographers standing on coral (not sand) to get their shots
-dive photographers holding onto coral (not rock) to steady themselves for their shots
One diver was trying to get photos of a circling shark. He was lying in coral and rolling all around to get his shots.
Unbelievable. National Geographic gives dive photographers a very bad name.
