Photo Essay Aug 3, 2012

The subject of the photo is a German Shepherd running in a field. To capture objects in motion, a fast shutter speed is selected to obtain the sharpest image possible. The picture has a slight "camera shake," as evidenced by the slight blur around the dog's body. Camera shakes occur when the camera is being held by hand. To prevent any blurriness the camera should be mounted on a tripod. Aperture is important to set things in or out of focus. This photo is taken outside and depending on the brightness the setting for aperture can range from f/8-f/11. The grass in the background is shown to be out of focus, a large aperture is used to restrict the depth of field. The lens used in the photo is a normal lens where the layers look similar to the human eye.
