Understanding Shutter Speeds

These two photos show my understand of Shutter Speed.

Slow Shutter Speed

ISO- 1600

Aperture-f/22.0

Shutter Speed-1/25

Fast Shutter Speed

ISO- 1600

Aperture- f/7.1

Shutter Speed- 1/250

When you look at her fingers you are able to see in the first picture they a blurry compared to the second picture where her fingers are clearly defined. This is because of shutter speed, which is the unit of measurement which determines how long the shutter remains open as the picture is taken. In the camera the shutter opens to let light through to the film or electronic sensor, and closes again to effect the quality of the photo. With a slow shutter speed the shutter is opened for a longer amount of time, meaning the motion in the photograph will be blurred. With a faster shutter speed the motion is frozen because the shutter closes quicker. The Exposure Triangle deals with light entering the camera and shutter speed controls how long the light is exposed.
