The Camera in Motion
My digital camcorder is small enough that I can take it almost anywhere. While we're driving to work, my wife will occasionally grab the camera out of my bag and start shooting anything that catches her eye: a brilliant sunrise, the way Seattle's skyline materializes on a foggy morning, rows of orange-tipped trees alongside the freeway in the Fall. Although we initially bought the camera to take with us on vacation, it has turned into an unofficial chronicler of our lives.
One of the advantages of a small camera is that it easily moves with you. However, when you're shooting, motion can become a character in its own right. Slowly moving across a scene imparts a different feeling than quickly scanning your surroundings, for example. This chapter addresses the most common ways of moving the camera to add motion to your movie, including the number one rule: don't move.
It's time to go watch TV again (hey, this moviemaking stuff is easy!). Turn to a scripted dramatic show and note how often the camera moves. I don't mean how often the camera is moved, which provides different angles of the same scene, but how often the camera is actually moving—not much. When it does move, such as when following a character through a set (The West Wing often uses this technique when transitioning between scenes), the movement is smooth and measured.
As much as possible, limit your camera's movement. You want action that emotionally affects the viewer, which is more likely to happen when the camera is stationary and focused on the contents of a scene. A shot that's bouncing, zooming, or otherwise sloshing about like a drunk at happy hour is a scene where the movement is distracting from the action. Of course, there are times when motion is called for: can you imagine reality-television shows like COPS or ER using stationary cameras? I imagine it's difficult enough to chase a suspected criminal down a dark alley and over a chain-link fence without asking him to pause for a few minutes while the crew sets up its lights and tripods.
Staying still has another practical benefit: excess movement causes blurring in your images (Figure 3.1). Our eyes do a good job of pulling detail out of motion blur, but there's a limit to how often they can tolerate fuzzy swabs of color streaking across the screen.
Figure 3.1 Sudden camera moves introduce blurriness to your footage. Try to keep the camera stationary for most of your shots, if possible.
