Every shot I take has some processing. My cameras are usually set to neutral in all fields, but this is adjusted to suit circumstances. If you shoot RAW, you have to do some adjusting, as RAW cannot be printed - it must be converted. Anyone shooting film has to convert, using chemicals. Shooting digital does it with electricity. Getting it right in the camera is just the start. To get the best image, you also have to get it right in PP. A lot of people who smugly say they don't do any post processing are wrong - they just let the auto functions do it for them. Often, I suspect, because they can't be bothered, or are incapable of learning to do so.
All jpeg images induce a degree of softness via compression, RAW shots do something similar, so the sharpness need to be recovered. Not doing so is like someone with less than perfect vision refusing to wear glasses.
There is nothing whatsoever `natural` in any photograph - it is an artificial construct. PP is simply an essential part of the construction process.
