this image is not cropped and no exposure correction applied to it
Location on Google maps Wikipedia reference Sevengill shark in the low-vis green water and kelp forest behind it. Another image which is very deceptive on the distance of shooting due to the use of fish-eye lens, ultimate space eater. Visibility on that day was about 4m, which means it's the distance to the kelp trees visible on the shot, and since shark itself was hit by strobe light sufficiently well it is about just one meter from the camera to it.
This is conclusion of the "sevengill shark week". Next week is the "penguin madness week" ! ^_^
