Photography has its origins in the 4th century BCE when a Chinese philosopher discovered the pinhole camera. In the 17th century the portable camera obscura was developed. The first permanent photograph was taken by Joseph Niepce in 1826 called View from the Window. In 1839 Louis Daguerre published a manual describing the daguerreotype process, an early photographic process using silver-plated copper sheets. Henry Talbot invented the calotype process in 1841, creating the first negative images.
