Look Dev Is Not Color Grading with the HAL Pictures Team

Look development and color grading share tools, but they are not the same job. We sit down with the Hal Pictures team — Martin Roux, Olivier Patron, Paul Morin, and Antoine Mayette — to dig into how a group of French DOPs, a DIT, and a director built the tools they couldn't find anywhere else: Diachromie and Diaphanie. The conversation starts where the frustration did. Post houses in France lacked proper look development infrastructure, and what existed elsewhere was either inaccessible or wrong for their workflow. So they built their own, rooted in a principle that any image can be decomposed into three parts: contrast, color tone curves, and color volume. Understand those, and you can describe a look. If you can describe it, you can build it. We break down Diachromie's approach to shaping the color volume parametrically inside a color-managed pipeline, and Diaphanie's frequency separation engine for texture — MTF, halation, bloom, and grain as independent, composable layers. The team explains why they separated color from texture, why that opens up aesthetics beyond film emulation, and why algorithm-based tools and sample-based tools are different propositions — not better or worse, just different. There's also a practical conversation about the limits of OpenFX, running multiple plugin instances to work around fixed order-of-operations, and how the preset system carries look development knowledge from project to project. These are practitioners who built for their own needs, then released it. That lineage shows in every design decision. Subscribe, share with a fellow color nerd, and leave a review.
