Wetpixel publisher Eric Cheng has posted footage from a GoPro HERO showing him freediving under a whale shark on Vimeo. The film was shot during the Wetpixel Whale Shark aggregation expedition near Isla Mujeres, Mexico in 2011. The 2012 Wetpixel Whale Shark trip is coming to an end tomorrow, so I’m sure we can expect lots of similar footage being posted on the trip’s forum thread.
