Didn't do any special post-processing; taken right before sunrise on a misty pond. I like the misty, painterly effect. They flew right when I got there & wasn't completely ready. Did manage to get to shutter priority and set a speed that would catch them - but then they were gone. Got away with it with the D70 & got three quick shots (tripod) whereas I'd have been lucky to get one with my CP5700 - such a difference in speed & responsiveness.
