What is the man teaching the woman?

M: Hold the body of the camera with your right hand, and the lens with your left.
W: OK. The view is blurry. How do I focus the camera?
M: Turn the ring in the lens in one direction until whatever you’re pointing at looks sharp. If that doesn’ t work, try turning it the opposite way.
W: Right. I’ ve got it. That’ s pretty neat. What else can you teach me?
