This scene combines three different atmospheric effects that normally don’t happen together .. lightning, a rainbow, and a dark sky. A rainbow forms from sunlight refracting through raindrops, while lightning needs strong charge separation inside storm clouds. The sky in the background is dark enough to show stars and the Milky Way only in long-exposure photography, which explains why everything looks visible at once. It’s not a single moment the human eye would naturally see .. it’s a blend cap
