I feel this so much. Despite telling her umpteen times till date, my mom will stretch photos only along one dimension to "fill the space" when writing docs or making slides. It drives me absolutely insane. She doesn't even realize till I tell her that the faces (and people) are stretched or squished too much.

Not to defend her preference, but faces (and everything else) can also look different depending on the focal length of the lens used and the distance from lens to subject, _and most people won't realise_.
