Ooh, i love this, it has such a stylish vibe!! It is tricky to just apply one LUT, but yes, I think it creates such a cohesive feel at the same time. I often do that, and then go in and just lighten/adjust the clips that need it.
I do feel the 3 second shot sets a good base, but yeah, it's hard to stick too, and can always benefit from a bit of tweaking.
I think I need to watch Ultimate Note.
