Hi Bob, I shoot thousands of aircraft images a year and this is rarely an issue if you use a simple formula. First is your placement in relation w/ the aircraft and the sun. The sun needs to as close to coming from your back as possible, and preferably low to mid over the horizon. Images shot with you on the shadow side of the aircraft are often just black holes in a dead sky. Since the aircraft are moving you need to set your shutter speed as fast as possible to ensure that the plane is sharp. Forget the junk about frozen props and such, the airplane itself is the subject do everything that you can to get it razor sharp. Obviously jets will require shutter speeds at or near your cameras limit. High speed passes and quick turns are hard to shoot sharp with out using 1/1000 - 1/4000 sec or so. The third part of this is to use as good a telephoto that you can get your hands on steer of zooms unless they are the high end factory goodies, the same with TC's.

The sky will be alive with the sights and sounds of virtually every type of aircraft in WA - commercial, military and executive jets, turboprops and piston-engine aircraft, vintage, ultra-modern and ultralight. >>> Karl Sounds a fantastic spectacle. Against the sky planes often come out jet black. What exposure will you use of will you just wing it? Let us see your best shot Bob PS The intitial "WA" might confuse the inhabitants of Washington. Wouldn't WOZ be better? ;o)
