I had big problems to took that image.
It was noon and the sun, at that time at the Equator on the white sand of the Maldives is as a great bad dog. It can assalut you and burn your white (or grey-city one as the mine) skin in few minutes. The reflection on the white sand was so strong to have an effect similar to capture directly the sun in the sky.
The colours of the laguna, so pale, were fantastic with all the tones of green and blue.
The totally absence of wind, so rare on a Maldives' atoll, have a dead calm effect on the sea surface.
Dead Calm is also the title of 1963 novel by Charles F. Williams, which was the basis for the 1989 movie, directed by Phillip Noyce with Nicole Kidman, Sam Neill and Billy Zane.
