This evening we looked at the Shutter and although this is covered in more detail in another post I would like to include some details about several of the techniques not covered.
Panning
This is a technique to enhance the illusion of movement. It works at shutter speeds between 1" and 1/30, sufficient time to allow the movement of the camera to blur the background.
The technique is achieved by following the subject with the camera at the speed it is moving and at the point that is parallel to your position fire the shutter continuing to follow through similar to how you might use a tennis racket or golf club.
This action will freeze the subject through the panning motion but the background will blur according to the direction of your camera.
A typical situation would be photographing a fast moving vehicle but can work with most subjects moving quicker than walking pace as demonstrated in the image by Michael Willems.
Multiple Exposure (using flash)
The other technique we tried although it wasn't as successful was using the flash to capture the movement of a subject. The scenario we attempted failed because there was too much light despite trying to find a dark shaded area, however later in the day or indoor the effect can be achieved successfully as Bruce Curtis demonstrates.
This technique is achieved by setting the shutter at a long exposure time (slow speed) e.g. 1" - 5" sufficiently slow to record multiple flashes.
It could be achieved using the built-in flash if it has the facility to fire repeatedly on release of the shutter but is more successful using a portable flashgun.
There will be more on flash in future session.
