Antique Dagerreotype, Ambrotype, Calotype, Tin-type, and CDV Photography of Ancestors. Please add the Ancestors that have this type of antique photography (100years old and over) uploaded to Geni.com- Must have the Attribution filled out completely.
Project is assist us in identifying different types of photos, appoximate dates that the different photos were taken. This is helpful when our relatives didn't write the dates on the inside of the cases or back of the photographs. Also, to encourage everyone to contact relatives and ask where are our ancestors images, who were they likely passed down to over the years. With cell phones it's easy to upload them to Geni.com and share with our relatives. For every photo that was taken of our relatives usually many copies were made for each family member. Duplicates may be found. If you know who the photogropher or studio was you must include the information. The studio and photographer may own the rights to all photography. The orginals can be sold, but we can't make copies and sell the copies. How Long Does Copyright for Photos Last? Image copyrights last for the duration of an image creator's life, plus 70 years after that. In the United States, image creators are generally granted what is known as a “Copyright Term” which lasts for the lifetime of the image creator and 70 years following their death.

How to identify a Daggerreotype and Ambrotype Photograph
(French: daguerréotype) was the first publicly available photographic process; it was widely used during the 1840s and 1850s. "Daguerreotype" also refers to an image created through this process.
Invented by Louis Daguerre and introduced worldwide in 1839,[3][4][5] the daguerreotype was almost completely superseded by 1856 with new, less expensive processes, such as ambrotype (collodion process), that yield more readily viewable images. There has been a revival of the daguerreotype since the late 20th century by a small number of photographers interested in making artistic use of early photographic processes.[6]
To make the image, a daguerreotypist polished a sheet of silver-plated copper to a mirror finish; treated it with fumes that made its surface light-sensitive; exposed it in a camera for as long as was judged to be necessary, which could be as little as a few seconds for brightly sunlit subjects or much longer with less intense lighting; made the resulting latent image on it visible by fuming it with mercury vapor; removed its sensitivity to light by liquid chemical treatment; rinsed and dried it; and then sealed the easily marred result behind glass in a protective enclosure.
The image is on a mirror-like silver surface and will appear either positive or negative, depending on the angle at which it is viewed, how it is lit and whether a light or dark background is being reflected in the metal. The darkest areas of the image are simply bare silver; lighter areas have a microscopically fine light-scattering texture. The surface is very delicate, and even the lightest wiping can permanently scuff it. Some tarnish around the edges is normal.
Several types of antique photographs, most often ambrotypes and tintypes, but sometimes even old prints on paper, are commonly misidentified as daguerreotypes, especially if they are in the small, ornamented cases in which daguerreotypes made in the US and the UK were usually housed. The name "daguerreotype" correctly refers only to one very specific image type and medium, the product of a process that was in wide use only from the early 1840s to the late 1850sDagerreotype / Ambrotype Photography Wikipedia
CDV The carte de visite (French: [ka%CA%81t də vizit], English: 'visiting card', abbr. 'CdV', pl. cartes de visite) was a format of small photograph which was patented in Paris by photographer André Adolphe Eugène Disdéri in 1854, although first used by Louis Dodero.
Each photograph was the size of a visiting card, and such photograph cards, in an early form of social media,[1] were commonly traded among friends and visitors in the 1860s. Albums for the collection and display of cards became a common fixture in Victorian parlors. The popularity of the format and its rapid uptake worldwide were due to their relative cheapness, which made portrait photographs accessible to a broader demographic,[2] and prior to the advent of mechanical reproduction of photographs, led to the publication and collection of portraits of prominent persons. It was the success of the carte de visite that led to photography's institutionalisation.[3] CDV - Wikipedia
Calotype photography is an early photographic technique invented by William Henry Fox Talbot in the 1830s.and introduced in 1841. The process involved coating a sheet of paper with silver chloride or iodide and exposing it to light in a camera obscura. Areas of the paper that were hit by light would darken, creating a negative image. The term calotype comes from the Ancient Greek words kalos ("beautiful") and typos ("impression"). The Calotype photos are a rare find.Calotype Photography
Check Silver and Gold plated lockets they were popular in the 16th and 17th Century for placing our ancestors miniature paintings inside. You can usually open the back, many of them have the names and dates inside identifying the people. Also, check the inside back of all photo cases for the names and dates. You can watch videos online how to safely do this without damaging the Image. Never open the seal tape, only the professionals should do this process.
