What is it?

In photography, the shutter speed or the exposure time is the length of time that the digital sensor inside the camera is exposed to light when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. 1/500 of a second will let half as much light in as 1/250. This gives the effect of either a fast or slow shutter speed, enabling photographers to experiment more with the type of photography they do.

Slow Shutter Speed

This is when the time of the shutter speed is longer to allow more light to be captured, this as a result makes the image less sharper and more lighter. it also often refers to a larger fraction of a second, such as ½ or ¼. Slow shutter speeds can capture movement and introduce blur, usually for slower moving subjects. Long shutter speeds are typically around one second or longer. This gives a example like this:

Medium Shutter Speed

This is when the shutter speed is in between a slow and high shutter speed as is around a shutter speed such as 1/250 to 1/30 sec. This is a middle ground, this mean the image is neither too bright or too dark but still gives the effect of a blurring/moving image, for example a medium shutter speed is used to blur a person running or animal giving the impressions of fast movement.

Fast Shutter Speed

Fast shutter speed is when you take a photo to 1/500th to 1/4000th of a second, This gives the image a sort of stuck in time effect with minimal or no blur at all. Fast shutter speed is often used to capture rapid moving objects or animals, this is so you get a clean image of a subject that would otherwise be blurred. But when you are using fast shutter speed the photo will be dark and lacking contrast. If you need a high shutter speed then you can compensate it with the aperture or if you don’t want to change that then you can increase the ISO value.

How the images were achieved

For the first image of slow shutter speed, I went outside the school and took pictures of cars going past. With the use of a slower shutter speed it made the cars look almost like a blur while the background stayed clear. This gave the illusion of the car going faster than it was. In the second picture it a gives and cool effect via the medium shutter speed, this is because only the legs are blurry but still not too blurry, this gives the idea of movement but only minimal. And with the third and final image it was just quite simple and shows a clear example of Freddie walking, but as it was a fast shutter speed, you are unable to see any type of blur even though he is moving.
