Last weekend I went to the mountains with my family for a casual mountain bike ride and witnessed this. There was a pretty big fire few mountains down the valley so when the wind blew towards us the smoke came over very very fast. I did not have my camera with me so I just used Open Camera app on my Samsung phone. The app limits the resolution for some reason but it creates DNG.

Here is my attempt in darktable:

Considering the quality of the sensor it looks not too bad but I could not find a good balance between getting rid of the noise and keeping details. Anyways here it is. If anyone is willing to play with the raw you are very welcome.
As usual, please use only open source tools and do share xmp,pp3, etc. files as well as processing comments/tips if you have a chance.
