By the time the details of this process were made public, in 1839, other artists and scientists had discovered additional photographic imaging techniques. William Henry Fox Talbot's Calotype process used light-sensitive paper and produced a 'negative image' that could be used to create positive prints.These methods required long exposure time, animate objects could not be recorded. No one could hold still long enough! The earliest photographic recordings were architechtural and landscape scenes.
The Daguerreotype picture above is from The J. Paul Getty Museum.
Since that time, photography has become an important tool in many fields, with sophisticated techniques and equipment continuing to evolve.
