ELI5: Why do some people look unattractive in photos, but look attractive when in person?
gpt
In converting a 3d image like a person into a 2d image like a photo, some features are lost.  Part of modeling is knowing which features to accentuate in order to look right on camera.  When taking a photo one might stick their chin toward the camera, it looks weird in person but it prevents the camera from making you look like you have a poorly defined chin due to the flat image.
