On which property does light a pinhole camera work? Pinhole cameras rely on light traveling in straight lines – a principle called the rectilinear light theory. That makes the camera’s picture appear upside-down. And from the description above we can infer that the pinhole camera works on the theory of rectilinear light propagation. So this is the required answer.
What is the difference between a pinhole camera and camera obscura? A pinhole camera, also known as camera obscura, or “dark chamber”, is a simple optical imaging device in the shape of a closed box or chamber.
