Furthermore, the photograph, which consisted of a single direct plate, was necessarily a reverse image, and on top of this, the reflecting surfaces othe plate itself interfered with viewing the image: according to how one held the daguerreotype, the picture flipped from a positive to a negative image. Salomon, who has devoted the last 18 months to mastering the not-so-lost art of the daguerreotype, plenty of room for invention remains in the process invented by Frenchman Louis Jacques Mande Daguerre. And in this contest, the new medium labored under numerous disadvantages: Daguerre's photograph, for example, reproduced the reality it sought to capture in very small format - and 'merely' in black-and-white as the early critics noted with disappointment as early as 1839. After Niépce's death in 1833, Daguerre maintained a partnership with Niépce's son Isidore but conducted his research independently.
Because daguerreotypes were unique objects, Meade made daguerreotype copies of the portraits that he judged to be popular with the art-buying public.

Daguerre had placed one of his treated copper plates in a cabinet that contained a variety of chemicals and was surprised to later find a clear image had developed on the plate. Boulevard du Temple, Paris, c.
While the daguerreotype fascinated Morse, he was concerned about how the new invention would compete with his telegraph. Daguerre too had had the idea to capture the images of the camera obscura.

Magazines and newspapers included essays applauding the daguerreotype for advancing democratic American values because it could create an image without painting, which was less efficient and more expensive.
A company was created to manufacture the equipment for making daguerreotypes, with one-half of the profits going to the manufacturer and the rest shared by Daguerre and Isidore Niépce. In January of 1839, the invention of a photographic system that would fix the image caught in the camera obscura was formally announced in the London periodical The Athenaeum. This goal led to his using bitumen on silver-coated copperplates and then iodizing the silver revealed after dissolving the unexposed bitumen. Designed solely for portraiture, this arrangement produced a far brighter image than a Chevalier lens, or even the later Petzval lens, but image quality was only marginal and the design was only practical for use with small plates. He became known as one of the fathers of photography.

Degotti at the Paris Opera and a thriving scene painter. Niépce's method was to coat a pewter plate with bitumen of Judea asphalt and the action of the light differentially hardened the bitumen.
