Hector Berrebi Masterclass

Day One ~ 4 Hours Jul 22, 2023

Toolset P1 - Laws of Perception

What is perception, how its inseparable of what we do in image manipulation, how does it guide our work, and how much can it be bent before its “broken”.

From rules of “black to pointer’s gamut” - breakdown of wrong & right and how we identify them.

Toolset P2 -  Blending Operations

Multiplying, screening & combinations

How to naturally and intuitively use various blending operations in your workflows and understand them without guesswork.

Toolset P3 - Nodes & Pipelines

A brief overview of the nodes and connections

Importance of image neutrality

Order of operations

Day Two ~ 4 Hours Jul 23, 2023

What’s a color model compared to a color space?

How are color models constructed and visualized?

Simple node Color Management – Working in Color Models

RGB to HSL, HSV, LAB and other models – strength and limitations.

DaVinci functions in RGB and so do most of its tools. How does changing this give us deeper levels of control and manipulation over our images? How do different color models offer us access to different parts and aspects of our content? How do some models stand out over others, what’s missing in Resolve and ways to overcome it, and why there isn’t one perfect color model.

Manipulating Luma and Chroma - the advantages of splitting luma & chroma parts of an image in different color models - HSL/V - Working in H & S for simpler & powerful hue & sat controls, manipulating luminance channels in LAB vs HSL, from contrast to exposure.

Manipulating Luma and Chroma in alternative ways - the recently introduced (18.5) per-node blending mode and how it can be used within this context - from simple limiters to advanced, nearly endless, possibilities.

Day Three ~ 4 Hours Jul 29, 2023

Intermediate node color management - blending and mixing channels.

What’s channel mixing? Splitting and combining to construct a channel mixer, mixing element within a mixer, and blending channels against each other - a different approach to exploring visual possibilities.

Intermediate node color management - the OFX Custom Mixer

Recently introduced to the DaVinci toolset, this effect hides quite a punch, how is it used and what are its strengths in our type of node structures and complex channel manipulations.

Intermediate node color management - LUTs, DCTLs, and other OFX tools

Important additions from the color inversion LUTs and OFX, to selected relevant  DCTLs and how to use them in our pipelines.

Day Four ~ 4 Hours Jul 30, 2023

Working in LAB - A deeper dive into LAB, its history, science, why it is different from other color models and relevant applications.

Advanced sharpening workflows and luma operations - texture manipulation and sharpening techniques on the L channels, the LAB unsharp mask node structure.

AB chroma manipulation - comparing and evaluating different known approaches. LAB vs YUV comparison and level of image influence and more.

(Advanced) Building and using LAB channel mixer - a challenging and complex exercise in advanced node structure and channel mixing - what can we learn from it and how can it be used in practical workflows.

CMY and subtractive operations – from basic to classic film look emulations.

What's CMY and what do subtractive operations mean - the role of CMY blending in film history and how it gained its special allure in glorious Technicolor - Is it even possible to “really” work in CMY and subtractive color mixing within an additive system? -

Different techniques and node structures to emulate the classic Technicolor look and how they are constructed using CMY blending and mixing.

Practical uses for look development and extras - the 15 channel color mixer.

Adding range limiters & clipping protectors.

Exploring texture based color and luma adjustments & manipulations, and more.

YRGB to ACES & RCM - how these techniques adapt within color managed pipelines.
