It was his visualization of a mobile, handheld camera obscura. That, of which, sent Níepce on his way into our history books. Zahn envisioned a simple structure using a reflective mirror positioned at a 45-degree angle to cast the image. He also added a flap on each side to block unwanted light.

How Exactly Do Camera Lenses Work? Lenses work similarly to the human eye and allow you to control the amount of light that enters your camera. Inside each lens is a series of convex and concave optical elements that work together to bend light and refract it into a single sharp focal point.
