I attached two I my first attempts shot with Fuji Supercolor 200. White balance is another story, getting the color of the film right (one of the reasons why I shoot film in the first place) is super hard. Inverting the base curve works, but adjusting the levels the same way as with b/w leaves me with a desaturated picture. While this works quite nice for b/w, colorfilm somehow doesn't work this way. After that I adjust the levels to get the picture to look less flat. Even with black and white film I get strange results, so I figured it's easier to just invert the base curve.

The first probelm I encountered was that the invert module in darktable doesn't really cut it. Since I'm using darktable anyways I thought I don't need that, I can just put some effort in creating some presets once for different films and use those afterwards. What I didn't realize was that most of them are using a lightroom plugin (NegativeLab Pro), which costs 100$. tiff scans are expensive), so I decided to scan the negatives with my K-3 myself - the youtube tutorials suggested that it's a fairly simple process.

I wasn't completly satisfied with the results of the scans my local lab provided (and high res.
