Are you Foto-Zenz? That’s a really cool blog post! Thank you so much for sharing it! I’ll have to experiment with your Darktable-chart styles!
Even with the “problematic” LUTs from Stuart Sowerby, I find it surprisingly useful to have a near-JPEG starting point. Actually I noticed that it is not that important to me that my starting point matches the JPEG completely. But having a rough approximation of what I saw in the viewfinder actually helps a lot.
Still, next week I’ll try to produce my own LUT with the help of @sacredbirdman’s program and see where that’ll take me.
