”DXR-G” Printing density characteristic for CINEON DXR files,
which captures the dynamic range of NEG films.
In addition to the DXR mode, the DXR-G mode provides
a closer color matching to the Kodak Genesis scanner.

Description
DXR-G
The DXR-G lookup table is the equivalent to the DXR LUT the same way as
TV-PD and TV-G.
Image data are mapped to printing density characteristics according to Cineon
DXR specifications.
The telecine setup should be performed similarly as described for DXR LUT,
but with the following differences:
1. First adjust (Lift) black and (Gain) white in the G-channel as described for
DXR.
2. Adjust matching Lift (black) readings for R- and B-channel to the control value
of the G-channel.
3. Adjust the black level for R- and B-channel with Matching Gain to 2%.
If the peak white level in one channel should be clipped, please take this chan-
nel as a reference for the first Matching Black and Gain adjustment instead of
G-channel.
