What are the corresponding Sony names for SonyCine709.png, SonyLC709-typeA.png and SonyLC709.png?

4_SGamut3CineSLog3_To_Cine+709.cube
2_SGamut3CineSLog3_To_LC-709TypeA.cube
1_SGamut3CineSLog3_To_LC-709.cube

Should linear REC2020 RGB be used for all 10 profiles?

For the film simulation luts the working space should be linear rec709

Print film simulation in Darktable

I’ve ported the Juan Melara’s lut to Darktable workflow Before the haldclut is necessary to use the unbreak input profile module with fixed parameter, the working profile must be “linear rec709” The usage is very easy: It helps activate the exposure module with exposure=+0.95 EV working profile=linear REC709 RGB Unbreak input profile (after the input profile) with the follow parameters [0unbreak] lut 3D with application color space=linear rec709

For Arri_logc3.png, is the output Arri Log C3?

The haldclut output is linear rec2020, pratically the haldclut does the following things:

logarithmic base 2 shaper to linear
rec2020 primaries to arri primaries
linear to logc3
apply the cube lut
pure gamma 2.4 to linear
709 primaries to 2020 primaries
