Hi Teo, thank you for your inputs! I know how log tools on log data behave and how to transform data from and to different color spaces but I question the accuracy of film emulation LUTs as the input data is different from project to project.
My initial question is, to be more specific - how precise / accurate is this film stock calculation after I have modified the contrast of the clip prior to the LUT. Not much of the film stock preference any longer I guess?
And, how precise / accurate is the film stock calculation as the input data (footage) change based upon the initial exposure levels, different camera sensors etc. How can the film LUT emulation creators claim that the LUT mimic a film stock 100% when the input data varies that much? I guess different exposure levels and camera sensors, modified contrast prior to the LUT etc will make the film stock emulation behave differently from time to time.
