By the late 1850s, the ambrotype was overtaking the daguerreotype in popularity ; by the mid-1860s, the ambrotype itself was supplanted by the tintype and other processes.

Previous discoveries of photosensitive methods and substances — including silver nitrate by Albertus Magnus in the 13th century, a silver and chalk mixture by Johann Heinrich Schulze in 1724, and Joseph Niépce's bitumen-based heliography in 1822 — contributed to development of the daguerreotype and the other silver based photographic processes that followed-collodion wet plate, and silver gelatin.

The popularity of the daguerreotype in the middle of the 19th century was due in large part to the demand for inexpensive portraiture.

Lost for a century, the daguerreotype was discovered in a warehouse in 1975 and was later determined to be the oldest daguerreotype in existence that was created by a Japanese photographer.

The daguerreotype had its problems, notably the fragility of the resulting picture, and that it was a positive-only process and thus could not be re-printed.

Astrophotography, the photography of celestial objects, began in 1840 when John William Draper took an image of the Moon using the daguerreotype process.

This gave it an important advantage over the daguerreotype process, which produced an opaque original positive that could only be duplicated by copying it with a camera.

In fact, the bitumen process used in private experiments by Nicéphore Niépce during the 1820s involved the chemical development of a latent image, as did the widely used daguerreotype process introduced to the public by Niépce's partner and successor Louis Daguerre in 1839.

It is also significant that, although the daguerreotype process was supposed to be free to the world, Daguerre secured a British patent on his own process.

The daguerreotype, was rarely used by photographers after 1860 and had died as a commercial process by 1865.

One person who tried to use the daguerreotype as a method of reproduction without Talbot's process was Levett Landon Boscawen Ibbetson.

The daguerreotype was a direct positive process and not reproducible.

The problem was resolved in 1851 ( the year of Daguerre's death ) when the wet collodion process enabled glass to be used as a support ; the lack of detail often found in calotype negatives was removed, and sharp images, similar in detail to the daguerreotype, were created.

The wet collodion negative not only brought about the end of the calotype in commercial use, but also spelled the end of the daguerreotype as a common process for portraiture.

The solar eclipse of July 28, 1851 is the first correctly exposed photograph of a solar eclipse, using the daguerreotype process.

The daguerreotype () was the first commercially successful photographic process.

The image in a daguerreotype is often described as being formed by the amalgam, or alloy, of mercury and silver because mercury vapor from a pool of heated mercury is used to develop the plate ; but using the Becquerel process ( using a red filter and two-and-a-half stops extra exposure ) daguerreotypes can be produced without mercury, and chemical analysis shows that there is no mercury in the final image with the Bequerel process.

An 1837 still life of plaster casts, a wicker-covered bottle, a framed drawing and a curtain — titled L ' Atelier de l ' artiste — has been claimed to be the first daguerreotype to successfully undergo the full process of exposure, development and fixation.

Although the daguerreotype process is usually said to have died out completely in the early 1860s, documentary evidence indicates that some slight use of it persisted more or less continuously throughout the following 150 years of its supposed extinction.

The daguerreotype process was far too slow to record anything but the brightest objects, and the wet plate collodion process limited exposures to the time the plate could stay wet.

The first known attempt at astronomical photography was by Louis Jacques Mandé Daguerre, inventor of the daguerreotype process which bears his name, who attempted in 1839 to photograph the moon.

The original daguerreotype is in the collection of the National Portrait Gallery of the Smithsonian Institution.

The view camera is a type of camera first developed in the era of the daguerreotype ( 1840s -' 50s ) and still in use today, though with many refinements.

The surface of a daguerreotype is like a mirror, with the image made directly on the silvered surface ; it is very fragile and can be rubbed off with a finger, and the finished plate has to be angled so as to reflect some dark surface in order to view the image properly.

When viewing the daguerreotype, a dark surface is reflected into the mirrored silver surface, and the reproduction of detail in sharp photographs is very good.

While it has long been accepted that D. W. Seager of New York City produced the first daguerreotype in America, it is unclear which other Americans may have been experimenting with the process prior to a public display of Seager's daguerreotypes in the Summer of 1839.

Note that this image is a mirror of Lincoln as he appears on the bill-this is because the daguerreotype process produced a single positive image ( rather than a Negative ( photography ) | negative made on photographic film | film, which is then used to make a true Photographic printing | photographic positive ), and the daguerreotype was always a mirror image of the subject material.

Silver iodide is always combined with silver bromide or silver chloride, except in the case of some historical processes such as the collodion wet plate and daguerreotype, in which the iodide is sometimes used alone ( generally regarded as necessary if a daguerreotype is to be developed by the Becquerel method, in which exposure to strong red light, which affects only the crystals bearing latent image specks, is substituted for exposure to mercury fumes ).

Daguerre took the first ever photo of a person in 1838 when, while taking a daguerreotype of a Paris street, a pedestrian stopped for a shoe shine, long enough to be captured by the long exposure ( several minutes ).

On July 17, 1850, Vega became the first star ( other than the Sun ) to be photographed, when it was imaged by William Bond and John Adams Whipple at the Harvard College Observatory, also with a daguerreotype.

The Sun may have been first photographed in an 1845 daguerreotype by the French physicists Léon Foucault and Hippolyte Fizeau.

The first photograph of a star was a daguerreotype of the star Vega by astronomer William Cranch Bond and daguerreotype photographer and experimenter John Adams Whipple, on July 16 and 17, 1850 with Harvard College Observatory's 15 inch Great refractor.

It was introduced in the 1850s and by the end of that decade it had almost entirely replaced the first practical photographic process, the daguerreotype.

This was an improvement over the calotype process, invented by William Henry Fox Talbot, which relied on paper negatives, and the daguerreotype, which produced a one-of-a-kind positive image and could not be replicated.

Bayard was persuaded to postpone announcing his process to the French Academy of Sciences by François Arago, a friend of Louis Daguerre, who invented the rival daguerreotype process.
