Introduction to Shutter speed

Shutter speed - definition
The time for which shutter remains open is known as shutter speed. For example, if shutter speed is 4 sec, then shutter will be open for 4 sec or you can say that the image will be captured after 4 sec (when shutter closes). Thats why while using low shutter speed, people are advised to use a tripod because till shutter remains open camera should be as still as possible. The range of shutter speed will vary according to model and make of camera.

In a camera, the shutter opens and closes to control the amount of light reaching the film. The longer it is open, the more light reaches the film. In a dark dreary place, you need the shutter to stay open longer to allow more light to reach the film. On a bright and sunny day, you need the shutter to stay open for a shorter time so as not to allow too much light to enter into the camera. Manually adjusting shutter speed can really be helpful in improving your photographs.

If you are shooting outside in moonlight or in a place where light is not sufficient, then you should increase your shutter speed to admit sufficient amount of light to camera which will make image more clear. If you are shooting in broad daylight or in more than sufficient light, then you should decrease your shutter speed otherwise your image will be very bright.
You should capture high speed motion in the fastest shutter speed that your camera provides.
 Lowering your shutter speed can create blur effect to show motion (which is sometimes very good).
