That's an interesting point. Retouching a photo after taking it used to be "manipulating reality", frowned upon by "real" photographers. Nowadays, postprocessing digital negatives and adding your own style to it is part of a normal photographer's workflow.

(However, I think the negative feelings don't come from a discussion of "real vs fake" or "classical vs new", but mostly from the point of view that using artwork as training data is stealing. I don't agree with that view, but I think it's at the core of the argument.)

People have been doing post processing of photographs as long as photographs have existed.

Yes, but - at least in landscape photography - there was a divide between people using retouching to "fix" things (i.e. removing spots, making the colors more realistic, etc) and the people altering the style of the photo (e.g. by boosting or even shifting certain colors to achieve a certain look). The latter was viewed as fake by some people I knew. Today this is just part of your photography style.

That doesn't mean there were purists arguing about it. Someone has to be doing it for the fight to exist.
