Help to create a set of "PIXLS.US" color LUTs ?

Processing

Time for a progress report :

  • We now have 32 CLUTs available in the pack. 31 of them have been compressed and included in the G’MIC plug-in (filter Colors / Color Presets, category PIXLS.US). This is pretty cool, and already enough to be distributed as a “Pack”.

  • The PseudoGrey CLUT cannot be lossy compressed without losing its pseudogrey property, so I didn’t include it in the plug-in (only compressed CLUTs can appear there). It’s not too bad as we also have a filter in G’MIC for converting images in B&W with pseudogreys.

  • I’ve updated the web page, with even more example and the 31 CLUTs visible : https://gmic.eu/color_presets/pixlsus_sample_9.shtml#browse

  • I can now generate a Pack of CLUTs, as a .zip file, containing:

    • The haldclut in .png format (all normalized to a 512x512 resolution, which means a 3D CLUT resolution of 64^3, which is already quite good).
    • The CLUTs in .cube format (Adobe ASCII format for storing CLUTs). It’s a crappy format, but I think some software can only read this. I’ve limited the CLUT size to 33^3 for the .cube files to avoid having huge files.

  • What we have to do next :

    • Decide what license we should use to distribute the Pack of CLUTs. Creative Common CC BY-SA everyone ?
    • Write a README file to put in the .zip archive, maybe add also a montage of all CLUTs applied on a single image, just to have a quick look of what it does ?
    • Set up a web page on PIXLS.US where we can put the .zip file of the PACK

Any suggestion and help is welcome !
