C200: Canon LUTs

Just re-read the readme(s) for 1D and 3D Luts and it seems to me the pertinent info - e.g. file format and naming conventions et al - is all there.

If you are asking about color science, that's a much bigger subject of which I am only a Padawan learner.

Brief elucidation of the LUTS:

Useful article: https://www.learn.usa.canon.com/resources/articles/2016/eosc300markii-colorspace.htmlp

HDR, ACES, WCG etc:

Sorry, my question was a little vague; I blame the fact I was typing on an iPad and too lazy to type more!

After downloading the LUT package, I get a directory with a lot of folders and files.

First, there's a 1dlut and a 3dlut folder. I understand that 3D LUTs are superior in most cases, so I'll ignore the 1dlut folder. In the 3dlut folder, I see 17grid, 33grid, and 65grid folders. After doing some more reading, I understand that the number represents the number of input and out points of the 3D LUT. In theory, the bigger number should be better, as it represents a higher accuracy. However, it's not clear to me if there's any downside on using the 65 grid LUTs.

Lastly, in each of the grid size folders are three folders: full-to-full-range, full-to-narrow-range, and narrow-to-narrow-range. In the full-to-full-range and full-to-narrow-range folders are a very similar looking set of LUTs. I'm assuming that the full-to-full-range LUTs are the correct ones to use, as they'd provide the post flexibility in my NLE. Is that correct?

Ok, lot of questions! Hopefully someone can provide some more guidance here.
 
I've never read the boring white paper, but I'll tell you which one I use... 33 gird, full-to-full.

I think the higher grid numbers require more processing power so might bog down your NLE.

I usually shoot a customised version of what is essentially the C-log2 preset (I just turn off NR) so in post I use 'CinemaGamut_CanonLog2-to-BT709_WideDR_33_FF_Ver.1.1.cube'.

I've just shot a job and the Alexa lut actually looks amazing on it, so I'll typically use either that or the Canon lut.

Which Alexa LUT are you using?
 
Just the one that's built into Lumetri 'ALEXA_Default_LogC2Rec709'.

Resolve also has it built in. Give it a spin.

Here's how it looks just playing in Premiere:

Those look fantastic and totally filmic. Thanks for the tip!

Hey man. Those are super great questions. It looks like you're getting help from a Canon rep in another thread, so I won't go in depth as I'm sure he can answer more precisely than I can.

In the spirit of education means empowerment, here's another article that might prove useful regarding LUTS and their applications:

On the outside chance you're not familiar with this book, I've also found reading and re-reading, applying and practicing the principles it lays out very useful:

Wishing you well with the exploration.
