AV size 22




The aperture of a lens is the diameter of the lens opening, the more light gets through.
The depth of field is the focus point, and so the bigger the aperture size gets the
more focused the picture gets.
I noticed that the way its focused when you change the AV sizes.
An Aperture of F22 is a smaller aperture.
An Aperture of F3.5 is a bigger aperture.
With shooting a crowd of people from different distances, and wanting it to all be clear, you'd have to use a aperture size of F22. By using F22 you'll get things from far away in focus as well as the things that are close up.
To get only a certain subject in focus only, i would use aperture size F3.5, because by using that you are able to get the subject you want in focus, be the only thing in focus.
