Camera - Page 18

A camera is an optical device that captures images or videos by recording light. It typically consists of a light-tight box or chamber, known as the camera body, with an opening called the aperture through which light enters. Inside, there is a sensor or film that converts the light into a visual representation, resulting in photographs or moving images. Cameras can vary in complexity, from simple point-and-shoot devices to advanced digital single-lens reflex (DSLR) and mirrorless systems, which offer interchangeable lenses and manual controls for a variety of photographic techniques. Additionally, cameras can incorporate various technologies such as autofocus, digital image processing, and connectivity features for sharing images. Overall, the primary purpose of a camera is to capture visual moments, whether for artistic, documentary, or personal expression.
