Help converting formula to RPN (LogC4 <> Linear)
Hello! Is anyone able to translate to RPN/Expr ARRI's LogC4 to Linear and Linear to LogC4 formulas found here?
https://www.arri.com/resource/blob/2...ation-data.pdf (page 9 under 'Reference CTL Implementation') Thanks in advance! |

No, not sure whether it helps, but https://www.arri.com/en/learn-help/l.../lut-generator has a link with a 3D LUT Package for LogC4.
