Amazing Underwater Video of Massive Sink Holes in Mexico Shot with Canon 5D Mark III

To shoot the video, White had to hack an old Aquatica 5D Mark II underwater housing to fit the new camera. (The new housings weren't available yet.)
Though the modified rig was functional, it only allowed him to access very basic controls on the 5D III including shutter speed, aperture, ISO, and the shutter release, which he reprogrammed to trigger the video mode.
Even with the limited control, White was very impressed with the 22.3-megapixel, 1080p-shooting 5D Mark III, particularly the "dramatically improved low noise capability" of the camera.
"When shooting the older Mark II, I find ISO settings above 640 produce very gritty shadows and banding in blue water backgrounds. Even when shooting no higher than ISO 640, the Mark II requires you to be spot on with your white balance and exposure techniques as any adjustment in post production will quickly degrade image quality. Many clips of large rooms in the cenote video were shot at ISO 2500 on the 5D Mark III with exceptional lack of noise."
