Daguerreotypes were made of copper plates coated with silver. The plates were dipped in an iodine fluid, which created the silver-halide "silver iodide." Silver halides are silver molecules bonded with halogens (elements that end in "-ine"). Silver bromide and silver chloride are also silver-halides. Why make a silver-halide? Because these compounds have a property of photosensitivity (light sensitive). As this coated plates dried, they were exposed to light, hence the reason for the silver compound. Afterwards, they were coated again, this time with Mercury heated to 75 degrees Celsius. Finally, they are put in salt water to finish (this part I don't know why it's done...). The final picture was usually put in a glass case to protect it; oils produced by the skin can cause copper to corrode.
I hope this information was helpful. If you need more information, feel free to let me know.

What is daguerreotypes?
A daguerreotype is a photograph made by an early photographic process. The photo was produced on a silver plate sensitized to iodine and developed in mercury vapor.
French inventor of an early photographic process in 1839?
Louis Daguerre introduced daguerreotypes in 1839.
Are daguerreotypes rare?
No, they are not rare but they are collected. Depending upon subject matter, the values vary but none are cheap any more.
Why were glass plates superior to daguerreotypes and calotypes?
Glass plates were superior to daguerreotypes and calotypes primarily due to their ability to produce sharper, more detailed images with greater tonal range. Unlike daguerreotypes, which were one-of-a-kind images on polished metal, glass plates allowed for multiple prints from a single exposure. Additionally, the wet plate collodion process used with glass plates enabled faster exposure times and improved sensitivity to light, making them more practical for photographers. This combination of quality and convenience ultimately contributed to their widespread adoption in the late 19th century.
What were pictures called back in the American Civil War?
You may be referring to daguerreotypes, invented by Louis Daguerre around 1826, which became popular around the 1830s to the 1860s.
What are the key differences between a daguerreotype and a tintype in terms of their photographic processes and characteristics?
A daguerreotype is an early form of photography that uses a silver-coated copper plate to create a unique image. It produces a sharp and detailed image with a mirror-like surface. On the other hand, a tintype is a later form of photography that uses a thin sheet of iron coated with a dark lacquer to create a positive image. Tintypes are more durable and easier to produce than daguerreotypes, but they have a lower image quality and lack the reflective surface of daguerreotypes.
What are the main differences between a tintype and a daguerreotype in terms of their photographic processes and characteristics?
A tintype is a photograph made on a thin sheet of metal using a wet collodion process, while a daguerreotype is an image produced on a silver-coated copper plate using a polished silver surface. Tintypes are more durable and easier to produce, while daguerreotypes have a higher level of detail and clarity.
Who. Invented. Camera?
I believe it was Louis Daguerre who is largely credited as the inventor of the process and apparatus to take "Daguerreotypes". This apparatus was the precursor to, and may be considered one of the first, cameras. At least that's what I was taught in high school.
What were early photos called?
Early photos were commonly referred to as "daguerreotypes," named after Louis Daguerre, who developed this first practical photographic process in the 1830s. These images were created on polished metal plates coated with light-sensitive materials and produced highly detailed, one-of-a-kind photographs. Other early photographic methods included calotypes and tintypes, which further advanced the art of photography.
What are characteristics of the daguerrotype?
The daguerreotype is an early photographic process characterized by its use of a polished silver-plated copper sheet as the imaging surface. It produces a highly detailed, one-of-a-kind image with a mirror-like finish, resulting in rich tonal variations and sharp clarity. The process requires long exposure times, often several minutes, and the final image is typically displayed in a protective case due to its fragility. Additionally, daguerreotypes are known for their unique depth and three-dimensional quality, which can create an almost lifelike appearance.
When photography was first invented it was limited to?
When photography was first invented in the early 19th century, it was limited to long exposure times, often requiring subjects to remain still for several minutes or even hours. The earliest processes, like daguerreotypes, used cumbersome equipment and toxic chemicals, making photography accessible only to a few skilled practitioners. Additionally, the images produced were monochromatic, lacking the vibrant colors we associate with modern photography. Overall, early photography was a complex and time-consuming process that restricted its use to specific contexts and audiences.
