Most traditional photographs are produced with a two-step chemical process. In the two-step process, the film holds a negative image, which is then transferred onto photographic paper as a positive image.
The
Ambrotypes
process a photographic process invented in the mid-1850s by Frederick Scott Archer. The process creates a glass negative, which appears as a positive when placed against a black background.
Cabinet Photos
came into being after the Civil War and remained popular until about 1900. Measuring approximately 4.5" x 6.5", they were larger than previous formats which made them easier to enjoy. The larger format also opened up new creative opportunities for the photographs. Early cabinets were mounted on fairly plain cards, but by the 1880's the cards had become more decorative.
Ambrotypes, Cabinet Photos, CDVs, Daguerreotypes, Stereoviews, Tintypes
CDVs or carte de visite is easily recognized by the small card on which the photograph is mounted. In this format, a small paper photographic print is mounted on a commercially produced card. The carte de visite (commonly abbreviated to CdV) today is not a rare item, being produced by the millions in the nineteenth century.
Magic Lantern Glass Slides"
In 1850, two Daguerreotypists in Philadelphia, William and Frederick Langenheim, invented a transparent positive image of a photograph in the form of a glass slide that could be projected onto a wall or screen using a Magic Lantern. The practice of using Magic Lanterns to project images on glass plates was by no means new. As early as the 17th century, glass slides had been projected using a Magic Lantern.
The
Daguerreotypes
is an early type of photograph, but, unlike modern photographs, it has no negative. Instead, it is an image exposed directly onto a mirror-polished surface of silver, (which has first been exposed to iodine vapour, or in the later use of the process, bromine vapour), housed in a velvet-lined folding case.
Sepia tone is a type of monochrome photographic image in which the picture appears in shades of brown as opposed to greyscale as in a black-and-white image. It was originally produced by adding a pigment made from the Sepia cuttlefish to the positive print of a photograph taken with any number of negative processes.
Tintypes
The ferrotype, also called the tintype or melainotype, is a photographic process developed in the United States in the 19th century. It superseded the ambrotype by the end of the Civil War and went on to become the most common photographic process until the introduction of modern "film"-based processes.
Stereoviews or stereoscopy, stereoscopic imaging or 3-D (three-dimensional) imaging is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. The illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. Many 3D displays use this method to convey images. It was first invented by Sir Charles Wheatstone in 1838.

The
Viewmaster system was invented by William Gruber, an organ maker and avid photographer who lived in Portland, Oregon. He had the idea of updating the old-fashioned stereoscope by using the new Kodachrome color film that had recently become available. View-Master was first introduced at the New York World's Fair of 1939.
