Once you have selected a subject you must decide how you
wish to convey the motion to your viewer.
The two main ways of conveying motion are:
Freezing Obvious Motion
Freezing motion is most effective when you capture a moment
that is obvious motion. For example, a person captured in
mid-jump with their feet off the ground or a surfer frozen
in the middle of a breaking wave. When the event is obviously
something that does not happen without motion, freezing the
motion is a great way to show a fleeting moment in time we
might not otherwise get a good look at.
Blurring Motion
Blurring motion helps to remind a viewer that motion is taking
place. Blurring motion works well with less dramatic action
such as flowing water.
Freezing motion and blurring motion can also be combined in
a single image under controlled conditions. Things like a
baseball player striking a baseball are good candidates for
this type of blending. When one subject is moving at a dramatically
different speed than another subject, it is possible to freeze
one while allowing the other to blur.
Shutter speed is the main tool photographers have for controlling
motion capture and blur. Shutter speeds needed to freeze action
differ greatly based on the subject and the subject's relation
to the camera. For example, to freeze splashing water you
may need a shutter speed of 1/1000 of a second or faster while
to capture a dog running towards you a shutter speed of 1/250
of a second may be all that is required.
Photography is the process of making pictures by means of the action of light. Light patterns reflected or emitted from objects are recorded onto a sensitive medium or storage chip through a timed exposure. The process is done through mechanical, chemical or digital devices known as cameras.
