Thank you my friends for your comments. The waves aren't always so beautiful in our region. But sunday there where a lot of wind and a fantastic blue sky with some great clouds, then the color was incredible. Usually, when the sea has this extreme blu color, it's because the water is very cold (very cold here... means about 12.... lol). I've just adjust the contrast and levels, all is natural ! Have a nice day. Hugs. Nathalie
