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.
