Swimming-pool, lagoon,… or simply Maldives ?

Swimming-pool, lagoon, or simply Maldives!!
No. This is not a Photoshop montage. This protected natural lagoon pool is one of the thousands amazingly shaped sandbanks of Maldives. This photo was shot a few months ago and could probably not be the same if I would photograph it again !
Indeed, according to tides and Maldives seasons (Maldives have 2 seasons called Monsoons) sandbanks constantly change their shapes due to currents. Some of them are moved away to another location, some disappear totally or for a while, and some other are born.
Who said Maldives landscapes are always the same ?
