Aperture & Depth of Field Photos

Practicing w/ Aperture and Depth of Field using DSLR’s

Due Wednesday Nov. 2nd

Objective:  Observe the difference in depth of field when a scene is captured with various aperture f-stops. 

Equipment: DSLR camera and tripod.

Instructions:

  1. Set your camera mode dial to “Av” (Aperture Priority) and your ISO to “AUTO”.
  2. Keep your lens completely zoomed out the whole time (18mm).
  3. Use a partner or an object as you subject and place them in the foreground of your shot.
  4. Find a location that has visual elements in the middle ground and background.
  5. Set up your camera and tripod between 1-2 feet from your subject. (As close as you can get while still maintaining focus of your subject.)
  6. Take a series of portraits starting with the lowest f-stop (3.5) and gradually increasing it one stop at a time until you use all f-stops (up to f22 for a total of 17 photos).
  7. Upload all your photos to your OneDrive.
  8. Format the card when you put it back in the camera.

Posting Instructions

Create a blog post the includes:

  • an explanation of aperture and how it affects depth of field.
  • explain the difference between shallow and wide depth of field.
