Capturing Motion...

A photograph is a static  two dimensional image. To give the impression of the speed of a moving object the background can be made into a streaky blur by panning the camera.

Another method of showing speed is by decreasing the shutter speed. The shutter remains open for longer and any body in motion streaks itself across the image :

The above picture shows a train moving at speed round a slight curve. It was taken in Manual mode with Aperture F/16 and Shutter Speed of 0.6.  You can also create such an image by following these steps :

1.  Use a tripod as slow shutter speed may result in the whole image being blurred due to camera shake.

2.  Change Mode Dial to Tv or Shutter Priority.

3.  Depending on the speed of the moving object experiment by selecting a slow speed and click the shutter.

4.  Try shooting in Manual Mode. First set the aperture to a large F number if the scene is brightly lit.  Then press the shutter button halfway and look at the exposure meter scale at the bottom of the viewfinder.  Rotate the top dial just behind the shutter button till the exposure mark below the scale is at zero. Then take the picture.

5.  Selecting a large F number makes the aperture smaller and then shutter speed has to be slower to correctly expose the picture.  The slow shutter speed results in the motion blur.
