Extreme DOF @fter Pan


Extreme DOF @fter pan, originally uploaded by imageo.

For some time I have realised that using anti-shake and auto focus while panning after birds in flight was counter productive. Most often I missed the great shot as the lens drives back and forth trying to focus or worse it would find something well in the background, behind the action and I have a blurred bird.  So I’ve been brave and stopped down a bit (eg f8 of higher, to get a bit of latitude in depth of field, DOF) and manual focussed in the middle distance where I expected the bird to fly. Then I set the camera into multi-shoot and follow the birds flight in a conventional smooth pan with my finger held down. Depending on the light I usually get a better sequence with just a little motion blur in the background (see below). However the photo above is the last shot in the sequence just as the sea gull is flying out of my depth field range and the distant background, well up the beach, is out of focus. Giving it a pleasingly ambiguous “into the unknown feel
