While I was up in north-west Scotland recently, I took a shot of a man walking his dog on a beach; both were quite distant from me. This morning I decided to print the image, and I took a closer look at the man's face, to see if I could get some detail there.
The first attachment shows the whole image. The second attachment shows the man's face, at 500%. Nothing extra was done to the face in post. The whole image got a 10% increase in contrast and blue/cyan got a 10% increase in saturation.
This is not a joke.
