My guess is the older the photographer the more they lean towards minimal post processing (and start waxing lyrical about the excitement of seeing an image materialise on a sheet of paper ).
I'm ancient but I enjoy seeing well done image manipulation.
I do find 30 year old hipsters, single speed bicycles and polaroids hilarious though.
