How many full stops separate f/2.8 from f/22?

Explanation:
In photography, a full stop in aperture represents doubling or halving the amount of light entering the lens. The standard full-stop sequence goes f/2.8, f/4, f/5.6, f/8, f/11, f/16, and f/22. Counting the steps from f/2.8 up to f/22, you pass through six transitions: to f/4, to f/5.6, to f/8, to f/11, to f/16, and finally to f/22. So, six full stops separate f/2.8 from f/22.
