I've found the official Canon C-Log conversion LUTs for my Canon EOS R6 here:
https://www.usa.canon.com/internet/portal/us/home/support/details/cameras/eos-dslr-and-mirrorless-cameras/mirrorless/eos-r6?subtab=downloads-software

I'm a bit confused on how to use them. I know that the workflow should be "Import footage → Input LUT → Color correct → Color grade with creative LUT", but there are so many input LUTs given by the Canon website and I cannot find a proper explaination.

Inside the downloaded folder I find the following sub folders:

• 1dlut

1. canonlog2-to-gamma-1dlut

2. canonlog3-to-gamma-1dlut

3. canonlog-to-gamma-1dlut

• 3dlut

1. 17grid-3dlut

2. 33grid-3dlut

3. 65grid-3dlut

If I shoot in C-Log3 and B709, which LUT is the best one to use?

And if I shoout in C-Log3 and Cinema Gamut?

I've read that the B2020 is for HDR monitors and it is better to use B709 because it can be seen properly also on SDR monitors, but between B709 and Cinema Gamut which one is more advisable to use? (I'm talking of both the camera settings and the conversion color space).

Thanks in advance
