3) Moire
Interaction between patterns can produce an additional "phantom" pattern to appear. The CCD picture
elements (pixels) are arranged in a pattern, which can interact with a pattern in the scene (e.g., a
performer wearing a finely striped necktie) to result in a Moire pattern. The effect should be considered
when selecting costumes, props and other scene elements.
4) Ghosting
Strong direct or reflected light near an object of interest can cause ghosting of the object to appear in the
picture. The effect is more obtrusive with certain iris settings and lens types. Select the scene layout
and camera pointing direction carefully in order to avoid this effect.
