I came across this guy's work and love the look and how clean it is. Besides removing the saturation, and strong clarity, what else is involved in getting this type of clean and detailed look?
What exactly do you mean by 'clean'?
From what I can tell, the post-processing they've used has included:
- Reducing orange street light cast either by using the temperature slider or red curves
- Boosted contrast
- Probably some image sharpening
- As has been mentioned in the comments, compositing has also probably been used
Oh, and the starburst effects around the stationary lights were achieved by using a small aperture (large f-number)
