Which has nothing to do with the technical limitations or physics of the sensor. If you want some B&W shot indicative of the 60's, sure it can be done. You just can't get the dynamic range the eye can see with a sensor, Nikon, Canon, whatever. There has to be PP for many types of shots.
What does matter is someone finding what that works for them consistently no matter what that is and thats really all that matters in the end.
