What is a 'Camera Obscura'?

A 'Camera Obscura' is a darkened enclosure used for projecting images. This phenomenon occurs when light from an external scene passes through a small aperture into a dark room or box, creating an inverted image of that scene on the opposite wall or surface. The principle of the camera obscura was foundational in the development of photography and illustrates the basic concept of how lenses work in cameras.

The ability to project an image allows for exploration into perspective, composition, and the interplay of light and shadow, making it a significant tool for artists and scientists alike in understanding optics and visual representation. The historical significance of the camera obscura as a precursor to modern photographic technology further emphasizes its relevance in the study of visual arts and perception.
