Aperture and Depth of Field

This slideshow requires JavaScript.

  1. How does changing the aperture or f-stop affect the LOOK of the picture? What is the relationship between aperture and depth of field?
    • Lowering the aperture will decrease the depth of field as well as the focal length, making objects in front of and behind the subject blurry.
  2. How does your focal length effect depth of field?
    • Having a wider focal length will slightly decrease the depth of field because there is less room to see the DoF
  3. How does your distance to the subject effect depth of field?
    • By getting closer to the subject, you don’t need to be zoomed in at all. This will increase the depth of field. Being zoomed in gives you a smaller focal length and  bigger depth of field.
