Note: To better illustrate the Parade scope’s analysis, the examples in this section are
shown with Broadcast Safe disabled so that image values above 100 percent and below
0 percent won’t be clipped.
The Parade scope makes it easy to spot color casts in the highlights and shadows of an
image, by comparing the contours of the top and the bottom of each waveform. Since
whites, grays, and blacks are characterized by exactly equal amounts of red, green, and
blue, neutral areas of the picture should display three waveforms of roughly equal
height in the Parade scope. If not, the correction is easy to make by making
adjustments to level the three waveforms.
