I actually discovered this by accident, just browsing photos on the internet.
I also saw an ad on Facebook for minimal black presets. After looking at one tutorial, however, I realized anyone could create these themselves.
To generate the above, I completely desaturated everything except red, yellow and orange. I then partially desaturated those colors and did whatever other adjustments to the photo I wished. In Lightroom I then created a new preset under the heading Glenn (my name) and called it Minimal Black RYO.
In Lightroom, once the photo is adjusted click on the + next to the word Presets.
After you click on the + you can add a new Group by clicking on Group, or add a new preset to an existing group.
I did want to see what I could do with the blue, green and aqua sliders as well, although the cyclists do look weird.
However, the landscape below seems to work.
I then tried yellow and blue, as there seems to be no real limit on how you can manipulate saturation. This too, came out well.
One more in the red orange genre was just before the Sturgis bicycle rally in SD.
