1816 – Nicéphore Niépce succeeds in making negative photographs of camera images on paper coated with silver chloride, but cannot adequately "fix" them to stop them from darkening all over when exposed to light for viewing.
1816. - Joseph Nicéphore Niepce je uspio stvoriti negative slika kamere na papiru obloženom srebrovim nitratom, ali ih nije mogao "učvrstiti" da ih spriječi da sasvim potamne kad ih se izloži svjetlu radi promatranja.
