  Parent was not talking about highlight reconstruction. DT has a highlight reconstruction module too but RTs was superior every time I tried. They're talking about the Filmic module which is a fancy exposure adjustment curve. I ported it to Rust for use in our internal 2D compositing renderer (not open, unfortunately). That's when I got to appreciate the work done there, really. The gainforge crate has another port, although not with all parameters of the original algorithm, AFAIR. The algorithm is explained in a blog post by the author of the module. [1] Who is btw. the same guy that got fed up with DT dev and forked it to Ansel.

    Thanks for the correction. After reading the reference I don't feel the need to pursue what seems a bit like a quest.
