Access to the aircraft at Duxford is unparalleled. Aircraft allocated to the flying display are parked just a few metres away from the viewing line, so close that you can feel the draft from their propellors as they start up for their display. So what do you need? Any digital Camera and a lens that is at least 300mm equivalent at 35mm used either hand held or with the assistance of a monopod. Like motor racing, if you want to achieve a sense of motion it is necessary to use a shutter speed that will not freeze the movement of the propellors. I find that around 1/200th to 1/250th suitable to give a subtle blur to the rotating propellor.
