We all have a (very tiny) glow of light, no movie magic needed

Normal cellular processes create biophotons, though the light is not visible to the naked eye

All the living things, including the plants and three people socializing and a fourth checking their phone, give off a bit of a glow of light while the rest of the illustration is shadowy.

The cells in every living organism produce minuscule amounts of light, though a visible glow-up takes some movie or illustrator magic.

Cornelia Li

Many science fiction and fantasy stories are enveloped in a warm glow, and it’s not just because of nostalgia.
