ELI5: Why do some pictures look like they are sharper and better than real life?
gpt
Real life has so much extra visual information that cannot be filtered out, which can distort the way things appear. For example, glare, unpolarized eye structure, differential strength between a person's two eyes, varying iris apeture, and most importantly, varied visual ability person to person. 

Cameras can filter out glare to make an image sharper. They can enhance color and brightness to correct for ambient light variations, they can used polarized lenses to reduce distortion from horizontal reflections etc.
