Photography began in the 1820s when Nicéphore Niépce captured the first photograph, though the process took 8 hours. Louis Daguerre later invented the daguerreotype, which sharply reduced the exposure time to around 30 minutes. In the mid-1800s, formats like the calotype and collodion process improved reproducibility and image quality. By the late 1800s, cameras became more portable and accessible to amateurs with the invention of celluloid film and Kodak's Brownie camera, popularizing snapshots. Photography has since transitioned to digital formats, allowing images to be easily captured, edited and shared on devices like phones.
