It happened in my career hunderds time to spot a whaleshark, and of course it is always an amazing encounter, but this time was special due to the light condition. we jumped in the water at the sunset cuase we saw the shape of a whaleshark, and after few minute the light became "pale blue" giving me the chance to take few shot before it becames too dark. And in those few shots the light gave me such incredible colour and atmosphere.
