good morning

Folks bugger that up all the time. Even if your middle grey is slotted differently it can botch a basic LUT.

Hey troy_s and se6astian. Was on the road the last days. Adding to your LiveGrade AIR discussion:

But compared to what a full color grading system can do it's just a small feature set. In general often even with on set grading the DI colorist will build the look again on his own to have it match his grading style instead of having a "magic" kind of LUT thrown on the material.

Good thing with CDL is: It's easy to implement and only some basic mathematics. For a homework I already implemented the CDL transforms.

The issue is that an input set of data is particular, and LUTs are heavily input dependent.

In a world that relies heavily on post production, having proper colour transforms is critical, especially for CG elements.

The only issue is that the input must match the contexts, something rather dice chancey if someone is using a third party LUT. Easier if within a known pipe

Those apps seem to be very snake oily.

troy_s: That's why I prefer a well defined workflow with ACES or something comparable.

troy_s: That's with every LUT, color transform etc. and not a thing specific for CDL

That's the thing people get out of camera on set most times so they use it ...

But sadly I suspect folks aren't quite aware enough of the input variables and probably think it is interchangeable.

You are right. For people not understanding color spaces and stuff may use it wrong or assume it does stuff that it wouldn't.

troy_s: That must be one of the reasons big postproduction houses have their technicians how setup everything before the session starts so that all is set correctlly beginning with the monitor color space, color space settings in the software etc.
