This repository provides a collection of open-source display rendering transforms (DRTs) and creative look transforms for professional color grading and compositing pipelines, specifically targeting DaVinci Resolve (via DCTL) and The Foundry Nuke (via .nk group nodes). The core functionality converts scene-referred imagery to display-referred output through a pipeline of gamut conversion, tone scale compression, hue processing, purity compression, and display encoding. It includes multiple DRT implementations (OpenDRT, Tesseract, Chromagnon, JzDT) with varying design philosophies, as well as a suite of look modification tools (ZoneGrade, NotoriousSix series, Nayatani HK, etc.) and utility transforms for gamut and log conversion. The code is grounded in color science standards (ACES, ITU-R BT.2100, CIE XYZ) and academic literature, with careful handling of edge cases through safe math functions. While the transforms are tightly coupled to their target platforms and lack automated testing, the shared header files (libDRT.h, libLMT.h) and standalone utilities demonstrate reusable patterns for color conversion and mathematical operations.
This repository provides Fujifilm camera profiles for use with raw images from digital cameras, specifically matching Adobe Camera Raw/Lightroom profiles for Fuji X-cameras. It includes DCP profiles, 3D LUTs (.cube files), PNG HaldCLUTs, and XML tables for various film simulations (Provia, Velvia, Astia, etc.). The system is designed to be used with linear camera profiles in applications like Adobe Camera Raw. The repository contains no executable code or software—it is purely a collection of data files (LUTs, profiles, and documentation) for color grading and film simulation. The DCP example file is a binary profile that would require dcptool to modify. The README provides usage instructions but the actual functionality depends on external tools like dcptool and compatible RAW processors.
