As this piece on The Passive Voice begins by remarking, there are lots of (mostly sad) stories to be told starting from the premise “people, including young people, can easily manipulate images of themselves before posting on social media, in an attempt to reach an unattainable, unrealistic, and harmful beauty standard”.

One story I just thought of: a teen subtly manipulates images of herself and her best friend to make herself look better and her friend look worse (to increase the contrast between them).
