    • Do one series without using any parallax correction, and one series with.

    Compare the results. Did the parallax correction remove all the parallax error, or just some of it?

  2. Read your camera's instruction manual, looking especially at the pages concerning exposure. Learn how to use these modes by finding a subject and take some shots using each of your camera's exposure modes.
     
  3. Read your camera's instruction manual, looking especially at the pages concerning focusing. Take a series of photographs using both manual and automatic focusing. Can you spot any difference in the sharpness in your results?
