The Art and Science of Photography

History of Photography

Photography has come a long way since its inception in the early 19th century. The first successful photograph was taken by Joseph Nicéphore Niépce in 1826, using a process called heliography, which involved long exposure times of about eight hours. The invention of the daguerreotype by Louis Daguerre in 1839 marked a significant advancement, making photography more accessible to the public.

Throughout the years, various technologies have shaped photography, including the development of color films in the mid-20th century and the transition to digital photography in the late 1990s, which revolutionized the industry.
