How to make use of shutter speed.

Shutter speed is one of the important ingredient in photography. 

Shutter speed is the length of time the camera shutter is open, exposing light onto the camera sensor. Essentially, it’s how long your camera spends taking a photo. This has a few important effects on how your images will appear.

When you use a long shutter speed, you end up exposing your sensor for a significant period of time. The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. This effect is used quite often in advertisements of cars and motorbikes, where a sense of speed and motion is communicated to the viewer by intentionally blurring the moving wheels.

Slow shutter speeds are also used to photograph the Milky Way or other objects at night, or in dim environments with a tripod. Landscape photographers may intentionally use long shutter speeds to create a sense of motion on rivers and waterfalls while keeping everything else completely sharp.

In other words we can say that faster shutter speed can freeze objects, while using the fast shutter speed the amount of light absorbed by lens will be less. Therefore there will a chance of darker image. To resolve this problem we should adjust the ISO. 

Fast, Slow and Long Shutter Speeds

A fast shutter speed is typically whatever it takes to freeze action. If you are photographing birds, that may be 1/1000th second or faster. However, for general photography of slower-moving subjects, you might be able to take pictures at 1/200th second, 1/100th second, or even longer without introducing motion blur.

Long shutter speeds are typically above 1 second – at which point, you will need to use a tripod to get sharp images. You would use long shutter speeds for certain types of low-light / night photography, or to capture movement intentionally. If anything in your scene is moving when you use long shutter speeds, it will appear very blurry.
