Photography is the art and science of capturing images through the use of light and a camera. It involves the process of recording visual representations of subjects, scenes, or moments, typically by exposing photosensitive material, such as film or digital sensors, to light for a specific duration. The captured images can be still photographs or moving pictures (video).

In photography, the key elements include composition, lighting, exposure, and the choice of focal length. Photographers use various techniques and styles to convey emotions, tell stories, or document reality. The practice can serve many purposes, including artistic expression, communication, documentation, and even commercial applications.

Photography has evolved significantly since its inception in the early 19th century, moving from chemical processes and film-based equipment to digital technologies that allow for instant viewing and sharing of images. Today, photography is an integral part of modern culture, utilized in social media, journalism, advertising, and personal mementos.
