Which device predates photography and projects an image when exposed to light?

• A. Camera lucida.
• B. Camera obscura.
• C. Pinhole camera.
• D. Magic lantern.

Answer: (B)

Light can form an image without recording it, and the camera obscura shows this in its simplest form: a dark space with a small opening through which light from the outside world travels and projects an inverted image onto a surface inside. This real-time optical projection happens long before any chemical photograph could be taken, which is why it predates photography. Artists used the optical projection to study scenes and draw them accurately, making it a foundational device in visual reality before cameras and film existed. The other devices serve different purposes: a camera lucida is a drawing aid that overlays an image onto paper rather than projecting onto a wall; a pinhole camera is a basic camera designed to capture an image on a photosensitive surface rather than to project a live view; a magic lantern projects prepared slides with a light source, not a live, unmediated scene.
