We made a cool tool that makes 17D lut's out of any PSD document setting. It's quite cool, give the DOP a 16bit tiff file in as a PSD file, let him do his grade to it in photoshop and save. Then we run that trough our script and get a grading setup usable in pretty much any pro grading /compositing tool like flame, nuke, resolve etc. It would be nice to be able to drag those into RCX aswell.
