Maybe that's a good source. There was another page on how to take airshow pics. I'm out of airshows for the immediate area for now and there's no airbases with really good flight ops nearby... I just need to work on tracking planes. And maybe deciding if my lens is a touch out of whack re: sharpness...
Air shows are better, much more colourful, I just saw these in the popular galleries, I'm sure Andy would answer some of your questions,his pictures are superb.
