Leica L-Log Reference Manual is a technical guideline for dealing with 10 bit L-Log footage. It introduces L-Log curve characteristics, colorimetric characteristics, L-Log to LSR conversion, LSR to DV and IRE mapping, color spaces.
This document serves as a technical reference for handling 10-bit L-Log footage, providing calculation specifications for converting between Linear Scene Reflection (LSR) and L-Log values. It details the mapping of LSR to Digital Values (DV) and IRE units, as well as the reverse conversion process.
| Color Space | ITU-R BT.2020 |
|---|---|
| Exception Model | Leica SL (Typ 601) |
| Exception Color Space | ITU-R BT.709 |
| Bit Depth | 10 bit |
It is meant as a technical guideline for dealing with 10 bit L-Log footage and defining the log curve used for recording.
L-Log uses the ITU-R BT.2020 color space, with one specific exception for older Leica SL models.
The Leica SL (Typ 601) uses the ITU-R BT.709 color space if it has Firmware Update 3.8 or above.
