Planes, trains and automobiles

Well done, Keith - this is an excellent first attempt at shooting moving aircraft. By setting a narrow aperture you've captured all the planes in sharp focus and your fast shutter speed has frozen the action. You've composed the shot well, which can be hard to do with fast moving subjects. The angle of the planes is great for capturing the curve of smoke trails behind, which adds a lovely shape and leads the eye in to the main subjects. We can also see plenty of detail and definition in the aircraft, which makes for an excellent dynamic shot.
