GENERAL
The LUT interface allows you to load any custom LUT as a primary grade on the image.
Use the Load button to select a LUT. LUTs must be in a format that SCRATCH can read. See the Chapter 11 - Customization for more details on supported LUT formats. The Create Curve button will transform the loaded LUT into a curve that can be viewed in the Curves menu - discussed earlier in this chapter. The By-Pass button toggles the use of the LUT on and off. The Reset button removes the LUT file reference.
