I'm a vfx guy, so excuse when my vocabulary isn't correct right away
As many here stated, the BMCC records a LOG-Image when using RAW or ProRes (I guess when using the Film-Mode, rather then Video that records REC709?). So, does anyone know which LOG this actually is?
Is it an own LOG, or Cineon, something like S-LOG? Alexa's LogC is a really mighty colorspace, which is the one that the BMCC uses, what is the correct curve?
Hope someone can settle this question.
I too, am a VFX guy - lol
I'd like to know the answer to this question too.
From my own experimentations, I believe it is unique to the BMCC, which would make sense as the color-space surely has to be relative to the dynamic range of the sensor, right?
I found this by re-rendering a DNG sequence to DPX's, reading them into Nuke and setting the read node to RAW - which essentially applies a linear curve to the image, giving you the LOG image without any grading. If you then put a colorlookup node on this, and apply a REDLOG, CINEON or Alexacurve, it should look correct, but it doesn't for me
Maybe we should post this somewhere else so someone more technical will see it?
