Hello, I currently have got some .cube lut files. For more control when color grading, I want to have the LUT in a RGB Curves adjustment layer. How can I do this?

 

This idea has been done in different programs, there is the video:

I have a working prototype conversion workflow... It is convoluted, so you really need to have need to do this!

 

Is the LUT file a standard Adobe .cube file? If so what is it's name?

 

If not, can you provide a download link for testing?

    After testing on another LUT based on film processing, there are more major differences in the conversion than the original LUT.

     

    Therefore, the simple and perhaps best answer is to just have the LUT adjustment layer in place, then add a curves or other adjustment layer on top and make minor tweaks, understanding that this is a compromise.

        What @Tuna5D34 requires is the opposite, a way to convert the .3DL file into an .ACV, or to manually recreate the effects of the LUT as a curve preset.

          Depending on the LUT that could be impossible. 

          Unless the OP provides the LUT it seems difficult to provide meaningful advice.
