The objective of this assignment was to take two sets of four photos that demonstrated the effect of changing aperture and shutter speed. (Click on the thumbnails to view the image.) In this set I was trying to display how shutter speed affects motion. With the slow shutter speed of 1/8 second, you can barely make out the pages, and the white blur indicates rapid movement. However, increasing the shutter speed allows the camera to get a quicker glimpse of the scene, lessening the motion blur and freezing the action. With a fast shutter speed of 1/250 sec, the camera is able to capture the pages as they are moving, and freezes them in place. They appear to be suspended in air and you can make out the detail on the pages. In this set I attempted to display how changing the aperture (the size of the lens opening) impacts the depth of field. With a large opening of f 5.6, the camera lets more light in, and creates a smaller depth of field. This shows a sense of depth, and you can tell the markers are different distances from the camera. The first marker is in focus and details can be made out easily, but the markers behind are blurred and out of focus. As you decrease the aperture, the depth of field becomes larger and more of the background is in focus. With an aperture of f 25, you can make out the details on all the markers, and it's harder to tell that they're not on the same plane. Fast shutter speed: Freezes movement, takes a quick snapshot of the scene. Slow shutter speed: Emphasizes movement, creates motion blur. Large aperture: More light comes in, small depth of field, blurs background and focuses on subject. Small aperture: Less light is let in, larger depth of field, more of image/background in focus.
