Shutter priority mode

This shooting mode is very useful when dealing with the problem of a moving subject. For example, a car traveling at a speed of 50 km/h is doing about 13.8 m/sec. So, if you use a shutter speed of 1 sec, you will obtain an image with background, but no subject!

At this shutter speed (1 sec.) the car has moved almost 14 m; in the best case you might get a trail of the shadow of the car… What you need to do is to freeze the action. To "make" the car appear to be still, you'll have to use a shutter speed of 1/2000 sec. Even at this shutter speed, the car has moved about 7 mm… not a very clear picture. So, if your camera allows it, you'll have to push the limits of the shutter to 1/4000 sec.! If not, wait for the car to stop.

However, the shutter can also be set for a long exposure time. This allows for the very useful effects, particularly useful for night photography. These long exposures always require the use of a tripod to steady the camera.
