troy_s: I looked at https://www.youtube.com/watch?v=1VX06UP5k7Y which can generate a ASC CDL (10 float values) to "pre define" a look
17:58
se6astian
they claim the input can be the smartphone camera, dslr or actual camera
17:58
se6astian
but am I right to say that a CDL file from a smartphone picture or DSLR will be completely useless for actual grading in post?
18:00
se6astian
if its not done with the actual camera that will create the final input image?

se6astian|away: Any sort of transform must match input.
21:50
troy_s
se6astian|away: So if it is purely a contrast look / curve, the input must match in terms of value range and curve or lack thereof. Log (whatever type, because there are several), linear, 709, sRGB, whatever.
21:51
troy_s
se6astian|away: And same applies (more so) for chromaticity styled transforms.
21:51
troy_s
(Imagine trying to use the 709 transform from the Axiom on a Sony for example.)
21:52
troy_s
TL; DR, if I understand the question correctly, yes.
22:01
troy_s
(Not that challenging to write such a thing with OCIO either. Take input image (value range and existing curve or lack thereof), twiddle and tweak.)
22:02
troy_s
(Then take exact same nodes that you twiddled and tweak, and apply it to an image with all RGB values in it.)
