Leica Q3 LUTs

Leica L-Log Reference Manual: L-Log puts 18% middle grey at 44% IRE (10-bit 445), and Leica's L-Log LUTs are built for that exposure. For best quality Leica recommends exposing to the right, then correcting exposure before applying the LUT. Internal ProRes L-Log uses video levels (64-940); H.264/H.265 use full range.

Camera settings

  • Video Settings > Video Gamma > select L-Log. L-Log records in the Rec.2020 colour space.
  • Leica lists native ISO 200 and 640 in L-Log.
