Shutter Speed


Shutter Speeds

Shutter speed is the speed that the shutter closes after you take a picture. The faster the shutter speed then the less motion blur there is in the image, this can give you a still.  The fast shutter speed also makes an image darker, this is because there is less light getting into the camera as it is opening and closing the shutter to make it faster. A slow shutter closes the shutter slower; this means that motion blur can be made because while the shutter is open it takes in what is seen. This means that you cannot move the camera as you will make the image blurred because it takes in the image taken. Slow shutter make the image lighter, this is because the shutter is open for much longer and takes in more of the light.


This is a bad example of a fast shutter speed. Even though the image is still, it is much too dark and you can’t see what you are looking at properly. This can be easily prevented by experimenting with different shutter speeds that will give you a different image. Also you need to look at how much lighting there is in the environment. If there isn’t enough then the image will be dark regardless of the shutters speed.


This is a better shutter speed picture. The lighting is good and it is a still. This was all down to the lighting of the environment. Because the lighting was much better and I had experimented with the different shutter speeds to make the image much clearer. A still like this is used in professional photography to try and catch fast things when they are moving. For example in Car or motorbike racing it is hard to take a good still of a fast moving vehicle like that.

Here is a bad example of a slow shutter speed. The image is so blurred you can’t see what it is meant to be. This is because it was taken when the camera was moving. When the camera moved it took all the light from where it was aimed, resulting in it not looking like a picture. To stop this blur you can have simply use a tripod, this prevents the camera from moving when the picture is bring taken.  The lighting of the images is good thought, it isn’t too bright which is what can happen if you have a very low shutter speed.

This is a much better image to show slow shutter speed. You can see the small amount of motion blur where it is needed. You can also see the rest of the image isn’t blurred, that is because I have used a tripod to make sure the image is still. The lighting in this is also strong, it is not to light or to dark, I think it is slightly better than the first slow shutter speed picture, this is because it has both highlights and shadow. This kind of image is used in professional photography to catch motion blur, motion blur makes something look like it is moving faster than it is.
