Yeah, I'm tired of watching 30 minute YouTube videos that I could've read in a few minutes. I grew up reading text tutorials for things like Photoshop and really wish they'd make a comeback
Glad you liked it! Yes darktable is amazing, though it can be intimidating at first. There's so many interesting things you can do with the modules and masking. I always wished for more text tutorials when I was starting out with it so trying to fill that gap now that I've used it for a few years.
If you like this effect, consider buying a Black Mist diffusion filter. On a lower strength, they really take the digital edge off, and on higher ones, they give everything a moody vibe.
The ones from K&F cost only 20 bucks and are a must have for me!
