The early history of photography began with artists in the Renaissance seeking to capture realistic representations of nature which led to the development of tools like the camera obscura. In the 18th century, scientists discovered ways to capture shadows using light-sensitive chemicals, laying the foundations for photography. The first permanent photograph was created by Joseph Niépce in 1826, while Louis Daguerre later invented the daguerreotype process in 1839, producing sharp metal plate images. Around the same time, William Henry Fox Talbot invented the calotype process using paper negatives, allowing images to be reproduced. Early photographers focused on portraiture and landscapes but their subjects expanded over time.
