Demonstration of imaging using a flashlight; a pinhole camera (camera obscura); a simple camera built from a lens, yogurt cans, and peanut cans; and a Kodak disposable camera. A pinhole camera and a single lens can both form images, and the images are upside-down. (A second lens, a prism, or a mirror is required to turn the image right-side up.)
