Understanding F-Stop

Understand F-Stop

It took me awhile to understand F-Stop. I kept thinking of numbers as backwards in my head. So every time I would try to take a picture I would think o.k. larger aperture number equals smaller opening – smaller aperture number equals larger opening.

Then it clicked This is how to think of an F-Stop…

The larger the F-stop the more light your aperture is blocking. The smaller the F-Stop the less light your aperture is blocking.

F-stop or aperture is an opening that controls the amount of light that is going to strike the focal plane.  Just like a film camera your digital camera records an image onto a focal plane. The lens focuses light through an aperture and shutter onto an image sensor that sits on the focal plane.
