To me the whole video was sort of a miss because he mistakes TE for being a 1:1 replacement for the other tools. It is not. Filmic sets the upper and lower bounds, something he does in tone curve by dragging in the points, then tries to do with TE, and sort of does, but TE works a lot better with filmic enabled.
Also note that he had a relatively flat and desaturated scene, and didn’t at all bother to set a color picker point and see what actually happened with a measurement. He eyeballed it and said “well close enough” and sure, you could probably get away with any of the three with an image like he uses.
Note that o was hard pressed to give up the LAB tone curve as well. I know it, I’m comfortable with it, I understand the way it works. But Filmic + TE is easier.I have old edits where the file is flat that I needed to use two masked tone curves to get it right. Filmic and TE let me add enough contrast that multiple modules aren’t necessary.
