A photograph is an image created by capturing light on a light-sensitive surface, such as film or a digital sensor. This process can be achieved using a camera, which focuses light to produce a clear representation of a scene or subject. Photographs can depict various subjects, including people, landscapes, and objects, and are often used for documentation, art, or personal memories. The invention of photography dates back to the early 19th century, with pioneers like Joseph Nicéphore Niépce and Louis Daguerre playing significant roles in its development. Today, photography is widely accessible due to advancements in technology, allowing anyone with a smartphone or camera to take and share images easily.
