Open Source Days 2026

This session presents two color-management case studies from Japanese 2D animation, based on Tomohiro’s work as a post-production engineer collaborating with production teams and introducing OpenColorIO workflows. The production case discusses a tailored OpenColorIO config and HDR/SDR tone mapping developed after evaluating ACES configs and ACES RRT. It focuses on preserving painted artwork colors while extending digitally created light and optical effects in HDR, and sharing SDR/HDR views between production and post-production. The remastering case discusses ADX encoding of film scans and LMT-compatible look design informed by print timing values, CMY dye transmittance, and projection light spectra. It focuses on reproducing color close to the original print while adapting a print-derived look for HDR delivery. The session shares reusable requirements and design patterns for OpenColorIO configs, HDR/SDR view design, ACES-aligned Look Transform design, and validation.
