By default, Vectorscope opens in Single mode:
Vectorscope can work in one of the available transform modes:
The appearance can be adjusted by setting the following parameters:
Colorize – toggle between color and monochrome traces,
Enhance center – gain applied to the middle part only,
Blend mode – various pixel blending modes,
Show HUE ring – can be visible/hidden, can also be dimmed down with “Dim down” option,
Vectorscope can be zoomed in and out using mouse wheel, and reset to 100% by either middle button click or double click the vectorscope area:
Vectorscope can be used in High/Mid/Lows split mode displaying a separate vectorscope for highlights, mids and shadows (lows):
By pressing Alt key you can preview what part of the image is monitored in which luminosity range:
Here's a quick animation - to see the real-time preview, hit alt key:
You can also change the split ranges in the settings and define your own Highlight/Mids/Lows luminosity ranges. It might be useful for low-key scenes where most of the pixels land in the lower luminosity range.
You can specify a maximum saturation range (UV vector length) and if the signal exceeds it OmniScope will display a warning (as a colored ring). You can also display a current maximum value displayed in real-time.
You can also enable Vectorscope outline which will show the signal edges more clearly:
