really nice results!!!
you pushed the idea to the limit
congratulations!!!!
I tried this palette as a consequence when the usual HOO or Hubble was named as "not natural" in any way by some colleagues. Really I am a fan of narrow band and tone mapping.
But I agree that when we use narrow band, it is never natural but with these parameters it tries to feel like regular RGB on asteroids!!
PD: thanks for the mention by the way
