Fantastic shot! Can you share your technical specs with us for that shot? I'd really be interested to know how you did that! Thanks.
I hope nobody will take those posts with explanation as flooding the thread :-)
Unfortunately I have to dissapoint you - there is a lot of PP in DPP (I don't think Lightroom would do it any better) and the original photo looks very very bad.
First of all this photo is one of four in a row, which were made in continuous mode with the use of AI Servo (the rest of them included below). The camera was 5d2, 70-200 F/4 L IS @200mm, 1/1500s, F4, ISO 400. It was cloudy, 4PM in Poland two days ago, the sun about 30 degrees to the left of the duck straight ahead. So it was almost behind the duck.
