So one question you need to answer is what is the LUT it output's transforming from? If the baseline is Linear then you can simply inverse it but it may not be that simple.
For step 4 I would look at 6.3v7's new Color>OCIO>OCIOFileTransform node which will let you inverse it pending it is only a 1d Lut (3d lut's can't be inversed). -deke On Sun, Apr 29, 2012 at 19:51, rsgca <[email protected]>wrote: > ** > Okay, so have I got this process correct? > > 1.
