  • At the beginning of the video, the aperture is 2.8. At the end of the video, the aperture is 32.

  • 1.

    Is there a pattern to how the aperture numbers increase from 2.8 to 32?

  • 2.

    How does the area of the circle change with each click as the aperture goes from 2.8 to 32?

  • 3.

    Look closely - is the aperture a perfect circle? Would the shape of this opening affect the picture?
