Film print emulation

Hello! So let's say i want to apply a fpe LUT for creative reasons. And i don't want it to tinker about with the contrast, i just want it to give me a colour response that that specific stock would give. I also want to apply it not as a LUT but as a 3x3 matrix in resolve with the channel math ofx plugin. Several questions to the pros here. Firstly how would i derive the matrix? Would this make sence and be better than just using a LUT? Does this sound totally insane and a complete and utter waste of time?

Thanks for the input

With the non-linear response of film a 3x3 matrix will not work.
It doesn't have enough control of the variables.

And i suppose that converting the material into linear in a node prior to that would not work would it because you trying to emulate a non linear response in linear digital world?

I should probably say that the silly questions are ispired by Steve Yedlin's showcase of alexa vs film and wanting to understand what is he doing special with the footage that it is matches so closely on many different scenes.

What info are you after?
What Yedlin did is very simple to emulate - nothing special there at all.

It is very simple to profile film response and then generate a LUT to copy that exactly.
Or, as Yedlin has done, just use a 'generic' filmic response rather thanone that is a profile of a specific film stock.

It is all just about gaining a 'look' that works...
