Cinematics of Camera Motion

• An animated zoom changes perspective, which can be disturbing and/or distracting. A dolly should be used instead to enlarge the image of an object of interest.
• The camera should almost never be rotated about its view direction--unless a seasick audience is the objective.
• Changing the focal depth can be used to track objects of interest, but a sophisticated renderer is required to simulate focus.
• Depth of field is rarely changed in real cinematography due to technical limitations, but might be useful in computer animation.
• Smooth spline animation should almost always be used for camera animation. Quick camera moves should normally be replaced by cuts (instantaneous changes of scene) unless a special effect is desired.
• Animation of spotlight sources is similar to the animation of a camera. Support of a ``light's-eye-view'', therefore, is often useful.
