How the hell can cameras capture a perfect still image of a scene?
In: Technology
There’s a mechanism in a camera that works like a curtain (called the shutter). Only this curtain can open and close extremely fast. Thousands of a second. That’s why the scene appears to be still. Behind the curtain there is typically a light sensitive film or digital light sensitive sensor that captures the scene for that very short period of time before the curtain closes again.
