Photoshopping is a 'modern' term. It was previously called retouching, airbrushing.
When you look are photographs in magazine and newspapers and see your favorite royal or celebrity with bright straight white teeth and no blemishes or pimples on their face, it is not because their skin is flawless or their teeth perfect.
Newspapers and magazines and online publications regularly retouch photos, especially of famous people. Wrinkles are removed, teeth are whitened and straightened, eyes are enhanced and made larger, faces are reshaped and double chins removed, bodies are reshaped and made slender.
Even 'historical' photographs were retouched.
In the U.S., people of color were regularly 'removed' out of photographs, especially if the picture was to appear on a cover of a magazine or newspaper, unless the article was about them This practice was still going on during the 1980s.
