Assignment: Depth of field
Set up a shot so that you have a subject in the foreground (close to you) and in the background (farther back). It can be two objects, two people or even one object or person that has a part of them/it closer to the camera and part farther back in space (for example, a person holding their hands out towards the camera to frame their face). Just make sure that you can see both the foreground and background subjects at the same time.
You will take 3 photographs of your subjects. Use a tripod and do not move your camera in between shots.
SHOT 1: Use a small aperture (large f-stop #) to create a large depth of field. BOTH of your subjects should be in focus.
SHOT 2: Use a large aperture (small f-stop #) to create a shallow depth of field. Use manual focus so that ONLY the subject in the FOREGROUND is in focus. The background subject should be blurry.
SHOT 3: Use a large aperture (small f-stop #) to create a shallow depth of field. Use manual focus so that ONLY the subject in the BACKGROUND is in focus. The foreground subject should be blurry.
