Scopes

Histogram

This mode displays a graph showing the distribution of color information in the pixels of the currently displayed image. The X-axis represents values of pixel, from 0 to 1 (or 0 to 255), while the Y-axis represents the number of pixels in that tonal range. A predominantly dark image would have most of its information toward the left side of the graph.

Use this mode to balance out the tonal range in an image. A well balanced image should a nice smooth distribution of color values.

Luma
Shows the luminosity of an image.
RGB
Shows the RGB channels stacked on top of each other.
R/G/B/A
Depending on the channel you choose the scope will show the appropriate channel.
Show line
Displays lines rather then filled shapes.

Waveform

Waveform Opacity
Opacity of the points.
Waveform Mode
Luma
ToDo.
Parade
The RGB channels are shown side-by-side.
Red Green Blue
Shows the RGB channels overlaid as a “Full color” waveform. It is useful for color grading.

Vectorscope

Vectorscope Opacity
Opacity of the points.

Sample Line

The Sample Line scope is the same as the Histogram but allows you to get the sample data from a line.

Sample Line
Used to draw a line to use to read the sample data from.

Scope Samples

Full Sample
Sample every pixel.
Accuracy
Proportion of original image source pixel lines to sample.
