Figure 6: On the Import 3D LUT dialog, select the desired colorspace and gamma targets for your

new 3D LUT.

The new 3D LUT retargeting function simply accesses the original saved display profile, re-

computes a 3D LUT interpolation to the new color space, and writes a new LUT file.

In just minutes you can have an additional 3D LUT to retarget your display to a new color space.
