Ever wondered how cameras reveal what’s hidden behind objects? This is called Lens Parallax — a stunning effect that happens when the camera moves and shifts its angle. In this video, the lens zooms past a pillar, and suddenly you can see someone sitting behind it. It’s not magic — it’s depth and perspective at work. The foreground (the pillar) and the background (the person behind) move at different speeds relative to the camera. That’s why something hidden becomes visible as the angle changes.
