Vectorscope

As of r21, it's possible to see if you’re going out of the scopes of your colour space.

Overview
Workflows

The Vectorscope plots the chroma of the image. Chroma is the colour information that is left when you remove the luma. This would typically be used to confirm colour accuracy against known test patterns, or to colour correct images objectively.

The Vectorscope has two overlays that can be combined or used separately:

  • RGBCMY - red, green, blue, cyan, magenta, and yellow markers at 75% or 100% saturation

  • IQ lines - aka the "skin tone" line, which can be used to correct skin tones

  1. Open the Feed Output window by clicking on Feed in the d3 dashboard

  2. Right click on the border of an output to open the Output Properties window

  3. Click on Vectorscope in the Output tab

The vectorscope may also be opened on a video input by opening the Video Input Patch Editor and then right clicking on a local input's thumbnail

This graph is a circular UV plot indicating where each additional pixel hitting at the same point additively increases intensity.
