Manjeet my Malysian mate this one's for you. Glad to have you back (now just stay away from that lightning....YOU HEAR - LOL!!! ;) :-O ).
As for the image itself the white Background is the unfortunate result of white clouds reflected in the water and exposure of the bird has resulted in a complete blow-out of it thanks to the sun beng in an awkward position too. I think it was something like 1/125. Anyway enough excuses from me (he he), it was still very close to my hide and an encounter I shall treasure.
