So I have to say that The Arri Look Creator for the Alexa is pretty awkwardly documented.
Is anyone loading custom Tone Curves into the program? Does Resolve or any other programs natively export the .lut file suitable for the Tone Curve?
I've been using a custom program to convert Cinespace CSP 1D LUTs to an Arri Tone Curve. The Arri Tone Curve seems like a list of 4096 values with no header or other identifying information so I assume it's a totally custom format just for the Look Creator. My process seems to work perfectly though.
