Part 3 โ Gain more control over color channels when color balancing
In this Insight, you learn how to build a custom node tree that makes our trackball balance adjustments behave subtractively, meaning the image gets darker as we push in any color direction.
Iโve always had difficulty quickly getting a โcolor washโ look Iโm happy with. I typically flip between wheels, trackballs, and secondaries to create something visually pleasing.
What Iโve realized after many years of doing this is that Iโm often looking for a subtractive feel, in which the images get darker as I push toward the โwashโ color Iโve chosen.
In this Insight, youโll learn to create a custom node setup that allows you to get that behavior automatically whenever you reach for your trackball. This allows you to dial in a great-looking โwashโ, quickly.
Youโll also build in the flexibility to toggle between subtractive balance and โnormalโ balance.
Premium Members: Download the CKC getMax v1.0 DCTL
Iโve provided a DCTL that captures the max RGB value of our three color channels, and sets all three color channels to that getMax value. We then use that getMax node in further image processing, as described in this video Insight. Mixing Light Premium members can download this asset from this Insightโs โAdditional Downloadsโ section.
Key takeaways from this Insight
By the end of this Insight you should understand:
- Why subtractive color is desirable, and why itโs often a better model for the behavior of real-world color
- How to perform basic โvisual mathโ with the layer mixer to get our desired behavior
- The difference between โnormalโ RGB balance vs subtractive RGB balance
