Royal Malaysian Navy (TLDM) commandos jumping into the high seas in an anti-piracy operation (demo) off Langkawi Island during LIMA ’11. The helicopter was a Westland WG-13 Super Lynx Mk.100.
If you want to capture motion blur of helicopter blades, you need to shoot below 1/250 sec shutter speed. Since I was hand-holding a 600mm lens, I kept the speed at 1/640. It was fast enough to freeze the soldier in mid-air and slow enough to retain slight blur in the tail rotor.
