Assignment #2b Shutter speed and motion

The camera has the unique ability to freeze motion or to show an entire motion to the point where it is only a blur.  Both of these qualities can be used in a photograph in interpret movement as you would like it to be shown.

A few things to remember are:

1.  A higher shutter speed will be required to freeze motion when the motion is parallel to the film than when motion is toward the camera.

2.  If you are using a slow shutter speed, those less than 1/30 of a second, you should use a camera support.  A tripod is best, however you can brace the camera on a bench, a wall, or place it on the ground.

3.  Panning means to move the camera with the subject in motion.  This will allow you to freeze motion which is faster than your fastest shutter speed.  Panning requires practice, so try this a number of times.

 1. Make a series of exposures that show the effects of freezing motion with a high shutter speed.

2. A series of exposures to imply motion using slow shutter speeds.

3. Finally  a series of exposures that  demonstrate the use of panning technique.

 Remember that you must adjust the f stop to match the shutter speed you have selected to get a correct exposure.  You may find that you can not use a low or slow shutter speed in the bright sun, as there is too much light present.  In that case, you must go someplace where there is less light or wait till dusk.  The same is true of high shutter speeds, which often require you to open the lens to get enough light to make a correct exposure, this may not be possible indoors, for example.
