A simulation of light is not the light itself.
When a digital sensor records a room, no physical artifact is created. Light strikes silicon, gets converted into electrical voltage, and is translated into binary code. An onboard processor then guesses the color, interpolates the edges, and writes a mathematical approximation to memory.
The resulting file is a heavily processed data proxy. In an era of algorithmic generation and synthetic media, pixels carry zero evidentiary weight. They are convenient, immediate, and weightless—existing on hard drives that eventually fail and cloud servers rented by the month.
