Comparing ARRI’s LogC4 LUTs To Resolve Color Management

Learn to customize the built-in color management workflow of Resolve with quality external LUTs. This series begins with ARRI's LogC4 LUT.

Using Custom Curves To Emulate Fill-Light Adjustments

Sometimes you want to 'open up' the shadows as if you added a bounce card or fill light to the scene. Custom curves make this easy.

Learning to Color Balance More Quickly With Fewer Adjustments

In the final episode of his 'Flexing Fundamentals' series, Cullen Kelly shows how to color balance more efficiently by thinking differently.

How do ‘Motivated Vignettes’ improve your color grading?

Colorist Cullen Kelly explores vignettes: What they do, when they’re appropriate, & how to deploy them in a motivated and photographic manner?

Contrast Adjustments: Which Is The Right Tool For You?

In Part 3 of Cullen Kelly's 'Flexing Fundamentals' series, learn how to think about organizing contrast adjustments to improve your results.

How To Upgrade Your Contrast, Pivot, Lift, and Gain Adjustments

Learn why colorist Cullen Kelly loves Contrast-Pivot for his contrast adjustments - and how you can upgrade them for more nuanced control.

Flexing Fundamentals: The Hidden Power of the Offset Wheel

In a new series on Primary color corrections, Cullen Kelly explores the hidden strength of the Offset Wheel - when working color-managed.

In Part 7 of Cullen Kelly's 'Visual Math' series, rebuild Resolve’s RGB Mixer with splitter/combiner nodes to control with Custom Curves.

How To ‘Trace’ a LUT’s Contrast Curve By Hand

Learn how to use Layer Mixer nodes to recreate a LUT's contrast curve for further creative manipulation in Part 6 of the Visual Math series.

Building Custom 'Lum vs Sat' Curves In HSL Using Resolve's Node Tree

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.

Extracting Only The Hue Or Saturation of a LUT using DaVinci Resolve

Learn how to extract the hue and/or saturation shifts of a 3D LUT, without getting stuck with the LUT's accompanying contrast adjustment.

How To Extract A LUT's Split-Tone Component Using DaVinci Resolve

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.

Build Your Own Qualifier In HSL Color Space Using Curves (In Resolve)

Learn an alternate method for creating masks limiting adjustments to particular luminance regions, using Curves and Splitter/Combiner nodes.

Building A Subtractive Saturation Node Tree In DaVinci Resolve

'Subtractive saturation' is a hot topic with colorists. Learn how to manually build this tool in DaVinci Resolve for more natural results.
