Who was the first inventor to take a positive image directly on ordinary stationery? What's his method called?

From 65438 to 0829, French stage artist Daguerre began to cooperate with Nipps to learn photography together. They lived in two places, conducted experiments separately and informed each other of the results. But Nieps died in 1833. 1837, Daguerre finally invented a perfect photography method-Daguerre photography (also known as "silver plate photography"). This photography method is a direct positive method which appears on silver-plated copper plates, and cannot be printed and reproduced. Daguerre believes that if the patent right for inventions like this is owned by individuals, it will never benefit the society. Only when the state acquisition is made public can it be completed immediately by the strength of all. 1839, the French government bought the patent right of this invention, and in August, Daguerre's optical photos were publicly displayed at the joint meeting of French Academy of Sciences and Academy of Fine Arts. 19 In August, the French government officially announced the details of the silver photography law, and Daguerre himself published a 79-page manual. Since then, photography has been made public, and August 1839 was designated as the birth day of photography. The silver plate method is considered to be the first practical photography method in the world. Although it could only be used to shoot still life at that time (because the exposure time needed 20-30 minutes), it quickly became popular all over the world. Whether in Paris or London, many people are crowded with optical shops and pharmacies, eager to buy cameras and negatives. Within a few months, new industries, new technologies, new art forms and new popular gadgets appeared in Europe. Almost at the same time as Daguerre, F.Talbot, an Englishman, also invented another photographic method-negative film method (also known as "Carlo photography method"), that is, the negative film was taken first and then developed into a positive film. He coated silver iodide on paper, put it in a mirror box, then developed it with liquid medicine to get a negative, and then printed it into a positive with silver chloride paper. But the paper film is opaque, so the effect is not ideal. I always feel that your question is not clear, so the above explanation is for reference.
