Exposure Triangle – ISO

Questions: Describe how you format an SD card using our DSLR cameras? What does AWB mean?

Learning Target:

  • I can adjust the ISO control of a DSLR camera and make five photographs using five different ISO settings.
  • I can post my pictures to my visual journal and reflect on what I see happening. What do you see differently about each picture? 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 close up. A location outside will work well.
  • Adjust the camera ISO from 100 to 6400.
  • Import your pictures using Adobe Lightroom and add them to your visual journal. Describe what you see different about each picture. Zoom in to each picture with Lightroom. Which picture has the least amount of noise? The most image noise? Do the colors and contrast of the images look the same?
