I got hired to do the color grading on a commercial that will be shot on a Red Epic so I grabbed some raw clips from reduser.com to do a quick test of how well visioncolor's m31 lut from Osiris would hold up with the r3ds.
The results are pretty amazing imo... literally just applied the LUT to all of the clips and made no other adjustments... such a great time saver!
