The National Georgraphic YouTube channel recently added this video featuring photographer Tom Campbell discussing capturing a shot of whale shark (Rhincodon typus) at Western Australia’s Ningaloo Reef. Campbell talks about how all the elements came into play just right to capture a “killer shot.”

While this video has been around for a few years on National Geographic’s site, as well as YouTube. This recently uploaded version appears to have significantly higher video quality than some of the past offerings.
