What is Aperture? A fall color inspired tutorial.

A very simple show and tell of the effect that aperture has on your image, and how it controls what is in focus (depth of field):

  • The image on the right was shot at f/2.0 at 1/8000 of a second- see how the background is out of focus? That is called a “shallow depth of field”.
  • The image on the left was shot at f/22 at 1/250th of a second. See how everything is in focus? That is called a “larger depth of field”.


The higher the f/stop (aperture number), the less light is let in, so that is why at f/22 you need a much slower shutter speed than at f/2.0.

Shoot a few images at extreme f/stops – 2.0 and 22 for instance (or whatever your lenses will allow).  Test it out to create interesting images, and let me know what you get over on the StonehousePhoto page!

    As I mentioned in my FB message, I’m a rank beginner, having mostly just gone with point ‘n shoot. With new people and animals coming into my life it seems like the right time to try for more! This is a perfect, simple start. I’m going to get my camera out and get started! Thanks for the inspiration, Hannah!
