Photography Question 

Barbara Helgason
 

Aperture


Please help me understand why a large aperture gives me a smaller depth of field than a small aperture. I understand the connection between the size of the opening and the amount of light entering the lens and how the SS is connected but I just don't get why it changes the depth of field. Can you explain it in simple terms?
Thank you,
Mrs Barbara Helgason
P.S. love your site, plan to take some lessons this winter!

  Hi Barbara.

This site:-

http://www.cs.mtu.edu/~shene/DigiCam/User-Guide/950/depth-of-field.html

Has a reasonable explanation as to why DOF changes with aperture.

Cheers
DC
