The document summarizes key developments in the history of photography from ancient times to the present day. It notes that camera obscuras were used as early as ancient times to project images. In the 16th century, lenses were added to camera obscuras to improve image quality. The first photosensitive compound was accidentally discovered in the late 18th century. Major developments then included the first photograph in the early 1800s, roll film cameras in the late 1800s, color photography in the early 1900s, and digital photography and camera phones in the 2000s.
