Camera techniques; Shutter Speed



Shutter speed is the measurement of time that light is allowed into the camera's shutter. This means that it effects the length of time that the camera is seeing the image it is picturing. Shutter speed, also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely, as seen in the above photo of the dolphin. If the shutter speed is slow, it can create an effect called “motion blur”, where moving objects appear blurred along the direction of the motion. This effect is used quite a bit in advertisements of cars and motorbikes, where a sense of speed and motion is communicated to the viewer by intentionally blurring the moving wheels.








My own example;



Shutter speed - 1/30


 Shutter speed - 1/250


Usually when filming the shutter speed it is better to shoot on 1/50 as 50 is two times the frames per second. Which means you should be shooting on 24 or 25 frames per second.

Although this is not the case depending on what you are shooting.

For example - shooting an athlete training or during a competition it is also better shooting on a fasted shutter speed. This will prevent the motion blur in which you can clearly see in my 1/30 shutter speed example.

Although if you wanted motion blur of a light source, such as; sparklers or cars the motion blur can make a really nice effect and look on your photograph or in your video.
