Feature requests, bug tracking, questions, and issues for Filmbox, Scatter, Screen, and Lattice. Also general questions about color science and filmmaking are welcome!
The image below shows how a neutral identity PNG Hald CLUT is rendered when opened via Open LUT….
The Identity LUT was generated by Lattice with the default settings (3D LUT, 33x33x33, 0-1 input bounds), and later exported as a PNG Hald CLUT (64x64x64, 16-bit).
Notes:
It works as expected if the Hald CLUT is exported as TIFF instead of PNG.
PNGs also work fine for the other image based LUTs export options (CMS Test Pattern Image, PNG 3D LUT, Unwrapped Cube Image), but not for Hald CLUTs.
