Darktable does a lot of things that are conceptually similar to what DaVinci Resolve is likely doing here.

One of the big things Darktable has been pushing for a few years is moving from the now deprecated display-referred workflow to a scene-referred one. The key idea is that you keep the image in something closer to the original scene as captured by the camera for as long as possible, instead of rendering it early into output-referred display space such as sRGB. With raw files that matters, because many editing operations behave very differently depending on where in the pipeline they happen.

That is a bit different from how tools like Adobe Lightroom tend to work. The main problem with display-referred workflows is not just reduced precision, but that you can end up clipping information and applying nonlinear transforms too early. Once that happens, later edits are working against damage that has effectively already been baked into the pipeline. So subtle tone mapping tweaks can push colors out of gamut, for example. There are a lot of ways to deal with that obviously and Adobe does a nice job of balancing tradeoffs. But they do remove a lot of choice and control from the process.

The UX tradeoff in Darktable is that module order matters a lot and there are a lot of different modules that do similar things in different ways. You can adjust modules in any order you like, but the processing order itself is usually best left alone. That is a leaky abstraction: it is hard to explain why the order matters unless you already understand what the pipeline is doing. And of course Darktable now allows reordering because there are sometimes valid reasons to do that. But that also means users can easily make things worse if they start changing the order without understanding the consequences.

But for simple editing, Darktable is actually really nice these days. I have some auto applied modules with rules for camera type and a few other things. Mostly it looks alright without me doing much. One of its strong points is rule based application of particular edits based on camera or lens. With my Fuji, it needs a little exposure correction because it under exposes intentionally to protect highlights for example.

I am a color science and image expert and couldn’t make heads nor tails of the dark table UI. I wanted to like it but it is just so horrible to use that I couldn’t stick with it.

Thanks for explaining this!
