Practicing w/ Aperture and Depth of Field using DSLR’s
Objective: Observe the difference in depth of field when a scene is captured with various aperture f-stops.
Equipment: DSLR camera and tripod.
- Set your camera mode dial to “Av” (Aperture Priority) and your ISO to “AUTO”.
- Keep your lens completely zoomed out the whole time (18mm).
- Use a partner or an object as you subject and place them in the foreground of your shot.
- Find a location that has visual elements in the middle ground and background.
- 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.)
- 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).
- Upload all your photos to your OneDrive.
- Format the card when you put it back in the camera.
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.
- a gallery of all the photos you took, captioned with the f-stop used for each (no need edit these photos).
- explain the experiment you just completed, and any observations made in the process.
