Whip pan. See Swish pan.
White Balance. e overall adjustment of the
relative intensities of the additive primaries (red,
green, and blue) with the goal of rendering colors
(especially neutral colors and skin tones) correctly.
White balance changes the overall mixture of colors
in an image. Our eyes and brain are very good at
determining what is white under different lighting
conditions, however, video cameras are not, even with
auto white balance (AWB) set. Incorrect white
balance usually leads to excessively blue images
outdoors or excessively orange or green images
indoor. Video cameras are usually white balanced by
pointing the camera to a white surface under the
current illumination and "setting" the white balance.
Cameras also have presets for daylight (5500K) or
tungsten (3200K) color temperatures. See also color
temperature.
Wide-angle lens. A short focal length lens that
enables the camera to photograph a wider area than a
normal lens. For 35mm lms a wide-angle lens is
30mm or less. Also called a short lens.
XDCAM HD. A high de nition video format based
on MPEG-2 used by Sony for storage of video on
some of their cameras, a higher-quality alternative to
the tape-based HDV format.
XLR. One of several sound connectors having three or
more conductors plus an outer shell which shields the
connectors and locks the connectors into place.
Found on professional audio gear and some prosumer
cameras.
Zebra (a.k.a. Zebra Stripes) is a feature found on
many video cameras used to determine exposure
levels. Diagonal lines appear in the view nder or
LCD display over any areas that are over-exposure.
Better cameras allow you to choose between different
zebra settings, typically 75%, 95%, or over 100%.
ese refer to the IRE video levels where 100 IRE
corresponds to pure white, 75 IRE is a very bright
area of the frame with textural detail, and 50 IRE is
around middle gray (or 18% grey in still photography
terms).
Zoom shot. A shot made with a zoom lens, which
makes the image appear closer (zoom in) or farther
away (zoom out) by varying the focal length of the
lens. Offers a very different quality than a tracking
shot. See Tracking Shot.
Zip pan. See Swish pan.
