Using the Luma histogram view, you can quickly compare the luma of two shots so that
you can adjust their shadows, midtones, and highlights to match more closely.
The shape of the graph also helps you determine the amount of contrast in an image.
A low-contrast image has a concentrated clump of values nearer to the center of the
graph. By comparison, a high-contrast image has a wider distribution of values across
the entire width of the graph.
• RGB Overlay: Combines waveforms for the red, green, and blue color components in
one display. If the image being examined has equal levels of two or more colors, you see
the combined color:
• Equal levels of green and blue appear as cyan.
• Equal levels of green and red appear as yellow.
• Equal levels of red and blue appear as magenta.
• Equal levels of red, green, and blue appear as gray.
• RGB Parade: Presents three graphs that display your video as separate red, green, and
blue components. The waveforms are tinted red, green, and blue so that you can easily
identify them.
You can use the RGB Parade view to compare the relative distribution of each color
channel across the tonal range of the image. For example, images with a red color cast
have either a significantly stronger red graph or weaker green and blue graphs.
