Problem
A project archive omits camera LUT metadata and exposure notes, making it difficult to reproduce the intended look from log footage.
Solution
Root Cause / Diagnostic:
Modern cinema cameras (Sony FX/Venice, Canon Cinema EOS, ARRI, RED) record in flat log curves designed for specific display transforms or custom show LUTs monitoring on-set. When projects are archived without recording on-set exposure indexes (EI), white balance kelvin, and monitoring LUT names, colorists must guess the original creative intent.
Actionable Fix:
1. Production Metadata Sheet Archival: Store digital camera reports, DIT logs, and on-set exposure sheets in a `/METADATA/CAMERA_LOGS/` folder within the project directory.
2. Camera Sidecar Metadata Preservation: Retain all camera-generated XML, sidecar files, and folder structures (e.g., Sony XDROOT, Canon CLOG metadata) without renaming source files.
3. Baseline Look Verification: Apply the manufacturer's technical transform (e.g., Sony S-Log3 to Rec.709) using documented on-set settings and verify exposure matches the original reference cut.
Pro Tip:
Never discard camera sidecar XML files or DIT sound/camera logs; preserving on-set exposure metadata and camera LUT notes saves hours of guesswork when matching log footage years later.
