ANGLE OF APPROACH
When you have a fast-moving subject, one critical issue is your camera position in relation to the movement. Things move slower in the frame if they’re heading towards or away from you, faster if they’re moving at right-angles to you. This falcon is a case in point: in the shot on the left, only the wing tips blur at a modest 1/250 sec with the camera steady, but in the diving sequence, it is flying at almost 100 miles per hour, and is only sharp thanks to a combination of downward panning and a shutter speed of 1/500 sec. This may make the head-on shot seem simpler to take, but focusing on a subject that’s coming straight towards you is much more demanding.
Two views of a peregrine falcon, one of the world’s fastest birds. In one, it’s flying almost directly towards the camera, and hardly moves in the frame, while in the other it’s flying at right angles, making a fast shutter speed vital
