A girl called Priya started using a filter on all her photos — the kind that smooths your skin, slims your face, makes your eyes bigger. She looked, in the photos, like a slightly different person: flawless, glowing, nothing out of place. The filtered photos got far more likes than her normal ones ever did. Soon she stopped posting anything without it. Then she started feeling strange about her actual face in the mirror — like the real one was the wrong one, and the filter was the right one. She's not sure when the filter stopped being a bit of fun.
