This lead to reducing the required camera exposure time from minutes to seconds and eventually to a small fraction of a second. Talbot had succeeded in producing a "sensitive paper" impregnated with silver chloride and capturing small camera images on it in the summer of 1835, though he did not publicly reveal this until January 1839. He capturing small camera images on it in the summer of 1835, though he did not publicly reveal this until January 1839. Talbot was unaware that Daguerre's late partner Niépce had obtained similar small camera images on silver-chloride-coated paper nearly twenty years earlier. However he did chemically stabilized his images to withstand subsequent inspection in daylight.</div>]]></description>
