Photography

Photography is the art and technique of creating images by capturing light. A camera records light reflected or emitted by objects and transforms it into a visible image, either on photographic film or through a digital sensor.

The word comes from Greek roots meaning "writing with light." Since its invention in the 19th century, photography has changed the way people preserve memories, document events, study the world, and communicate ideas.

The first permanent photographs were created in the 1820s, and the technology continued to improve with faster films, better lenses, and digital systems. Photography combines technical knowledge and artistic choices.

Photographers work with elements such as focus, exposure, composition, perspective, and lighting to create images with a specific purpose or meaning. It is used in many fields, including journalism, science, medicine, history, advertising, and everyday communication. Digital photography has made image creation more accessible, while new technologies such as smartphone cameras and computer-based image processing continue to transform the way photographs are produced, shared, and understood.
