Practical DV FilmMaking
The result is that your friends are going to be in focus most of the time. If they move a great deal within the frame that's fine, as long as they move across the frame rather than close to or further away from you. But if you had left the auto focus switched on continually your friends would be switching in and out of focus every time they vacated the very middle of the screen. So, in this case, you use auto to get what you want, then get rid of it. Now you are in control of the camera.
Evaluation
This project is unusual compared to the others in this book in that it relies very much on improvisation and on making mistakes. At each step of the way, you are wresting control from the automatic settings of the camera and seeing what happens when you shoot against the way it suggests. After all, the settings it gives are simply designed to give you what is considered to be the closest representation of reality. But in most filming you are trying to create illusions, to improve reality in some way, and so it becomes crucial to defeat these realist tendencies in the camera. You know where they are if you need them.

To stretch your skills further, try combining two or more manual controls - for instance, combine the iris with shutter speed, or focus with aperture. These combinations enable you to create new effects, such as the way increasing the shutter speed reduces light entering the lens in much the same way as aperture.
The theme in this movie is designed to offer an easy route, but you could try combining this with another project so that you make a film from elsewhere in the book but solely using manual controls.
