Picture taking: aperture and shutter speed settings

Lesson details

Learning outcome

I can use aperture and shutter speed settings to control light and blur in my photographs.

Key learning points

  1. Cameras work by allowing light to pass into a camera and onto a light sensitive surface.
  2. The f-stop or aperture controls allow us to change the size of the opening.
  3. The shutter speed allows us to control how long the aperture is open.
  4. By using both of these, we can control how light or dark our photographs are, and can reduce or manipulate blur.

Keywords

  • Aperture - The hole through which light travels in a camera lens

  • Shutter - The part of the camera that opens to allow light through the aperture

Common misconception

Changing the aperture or shutter speed only affects how bright the photo is.

While both aperture and shutter speed do affect exposure (how light or dark a photo is), they also have creative effects on how the photo looks, such as blur.

Teacher tip

Use addtional side-by-side visual examples to show not just exposure changes, but also creative effects.
