Understanding the QuickTime Source Settings Histogram
The histogram in the Source Settings window helps you visualize the distribution of color values
in an image. You can use the histogram to adjust the Source Settings of your AMA media more
precisely while avoiding clipping and color imbalance.
Example of a Source Settings histogram. The histogram plots color values on the horizontal axis and the
percentage or proportional number of pixels on the vertical axis. The vertical lines represent the black point (left)
and the white point (right), so the area between them is the safe color range.
The histogram plots color values that can be represented by the image bit-depth on the horizontal
axis. Therefore, the width of the histogram is the same as the width of the image. The histogram
plots the percentage, or proportional number of pixels in the image, with each particular color
value on the vertical axis. The vertical axis is scaled according to the height of the maximum
value in the plot. Whenever the histogram changes, the vertical axis rescales according to the
new maximum.
