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!
