Does this have anything to do with Night or Dust... no. I just thought the name sounded cool. As far as the "style" I just liked the overall aesthetic of the images used for training, there wasn't any specific style I was going for, I was just using images that I thought looked cool honestly. I've done a few tests to show the differences between flux dev with and without NightDust. If you want to see those comparisons then you can do so HERE
