When photographing a moving subject, you will get photos which are blurred, due to a use of an inappropriate shutter speed. This blur is called motion blur and it produces the effect of something leaving a trail behind itself when moving. Capturing movement in images is something that many photographers only think to do when they are photographing sports or other fast moving subjects.

There are 2 techniques used to achieve such an effect, both of them rely on the appropriate shutter speed to be used.

Moving subject/Still camera:
The first technique consists of having the camera completely still while the subject is moving. This will make the background or the setting of the photograph appear perfectly sharp and the motion blur effect will only be visible on the moving element.

Moving Subject/Moving Camera:
Panning consists of moving the camera in accordance with the movement of your subject. It will make the background blurred while leaving the subject in focus.
