Leica SL3-S 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 Profiles > Profile [1-5] > Settings > select L-Log (lower left). L-Log records in the Rec.2020 colour space. HDMI RAW is set with Format = RAW.
  • Leica lists native ISO 400 and 2500 in L-Log. The spec sheet gives manual and Auto video L-Log ISO 400-100,000.
