Colour Management – A Bird’s Eye View for Digital Artists
summary
Shows a practical pipeline: capture bracketed panoramas with chrome/gray balls and a color checker, combine into EXR HDRI scene‑referred maps, author materials in linear ACES space (ACEScg or ACES2065‑1), then apply the ACES RRT+ODT to avoid sRGB clipping. Demonstrates a mannequin digital‑double workflow, spectral tests (Macbeth boxes vs sRGB) and examples where sRGB clips highlights while ACES preserves extreme values (sun ~200,000 vs indoor light ~30), enabling reusable HDR-ready assets and fewer remasters.
