Exposure Triangle – Aperture

Questions: Describe the difference in each of your pictures when adjusting the shutter speed of your camera from 1/15th, 1/60th, 1/125, and 1/500th.

Did you achieve a proper exposure (too light too dark)? Good image sharpness?

Add four pictures to your visual journal showing a difference in each picture depending on the shutter speeds you selected.

Learning Target:

  • I can adjust the aperture control of a DSLR camera and make five photographs using five different aperture settings.
  • I can post my pictures to my visual journal and reflect on what I see happening with the different aperture settings. Describe what you learned.



  • Set the camera mode dial to Av (aperture priority) and use a 55mm focal length.
  • Go to a relatively bright location and photograph a subject (like flowers) with a consistent background. Use rule of thirds! Outside should work well.
  • Set the camera ISO to 400 or 800 depending on the amount of light available.
  • Take four pictures at four different aperture settings (f/5.6, f/8, f/11, f/16 and f/22)
  • Import your pictures using Adobe Lightroom and add them to your visual journal. Describe what you see. Which aperture setting provides the most depth of field? The least?
