I wonder is there any way to Add custom camera response functions?
From .cbf or Lut's is it possible somehow to convert these .txt extentions that Indigo uses right now??
Just wonderin..

Re: Camera Response Functions
Those camera functions are from here:

Maybe there is spreadsheet rule for that or sth similar?

Thanks Eneen.
Re: Camera Response Functions
Here is agfapan-apx-400CD green channel chart. As you can see importing camera response is quite easy.
It might be possible to create function in calc that interpolates e.g. 10 points into 1024 points with spline like this:

Idea is to create spreadsheet with preview chart where you enter mentioned 10 values and get 1024 ready to put into file.

Re: Camera Response Functions
Thanks Eneen!
Glad you have kept this question in mind!
Will check this out. Actually i managed to pull data inside Indigo from Lattice.
https://lattice.videovillage.co Not perfect still, but **kinda works.
Will have a look again if i find a bit of time.

Re: Camera Response Functions
If you have a good source of data for response functions and LUTs, it shouldn't be too difficult to add support for it in Indigo, especially now that we have colour curves (which is pretty much the same thing).
Re: Camera Response Functions
One of sources can be adobe dcp profiles from cameraraw (lightroom), available also with dng converter. Although dcp beside standard uses film-like curve that keeps hues constant. But I don't know how to extract tone-curve from dcp.
