152 Chapter 8 Video Scopes
Vectorscope
The Vectorscope shows you the overall distribution of color in your image against a
circular scale. The video image is represented by a graph consisting of a series of
connected points that all fall about the center of this scale. For each point within the
analyzed graph, its angle around the scale indicates its hue (which can be compared to
the color targets provided) while its distance from the center of the scale represents
the saturation of the color being displayed. The center of the Vectorscope represents
zero saturation, and the farther from the center a point is, the higher its saturation.
If the Monochrome Scopes option is turned off in the User Prefs tab of the Setup room,
then the points of the graph plotted by the Vectorscope will be drawn with the color
from that part of the source image. This can make it easier to see which areas of the
graph correspond to which areas of the image.
