Tutorials by Cullen Kelly
In Part 5 of our 'Visual Math' series, learn how 'vs. Curves' work from within Resolve's node graph by building your own in HSL space.
Learn how to extract the hue and/or saturation shifts of a 3D LUT, without getting stuck with the LUT's accompanying contrast adjustment.
Learn how to isolate the color impact of a LUT from its luma component to craft the image to your preferences, all within DaVinci Resolve.
Learn an alternate method for creating masks limiting adjustments to particular luminance regions, using Curves and Splitter/Combiner nodes.
'Subtractive saturation' is a hot topic with colorists. Learn how to manually build this tool in DaVinci Resolve for more natural results.
Cullen Kelly wraps his 10-part intro series about Coding DCTL. It's a live Q&A session answering questions, while Cullen learns something new!
Colorist Cullen Kelly finishes off coding a split-toning Resolve DCTL plugin with a visual overlay showing how the RGB channels are modified.
Colorist Cullen Kelly finished defining his Davinci Resolve DCTL plugin. Learn how he tweaks the interface, eliminating 'dead zones.'
In Part 7, Colorist Cullen Kelly shows how to add split-toning into the custom DCTL. Then he debugs and commits it to the main GitHub branch.
In part 6 of his ongoing series, Cullen Kelly explores how to combine two separate DCTLs for increased user functionality without adding complexity.
In part 5 of his ongoing series on coding DCTLs, Cullen starts to get into the thick of the tool he's creating - exploring how to define and code contrast.
In part four of his ongoing series on creating DCTLs, Cullen Kelly builds upon work done to create a static DCTL by adding user adjustable controls.
In part 3 of this ongoing series, with foundational knowledge in place, start coding your first DCTL a colorist Cullen Kelly guides you step by step.
In Part 2 of his series on coding DCTLs, Cullen Kelly covers some additional setup and tools you'll need to successfully build DCTLs
