The term “case photograph” describes three types of 19th-century photographs that were generally kept in cases which were both decorative and protective. They are the daguerreotype , named after its inventor L. Daguerre; the ambrotype; and the tintype or ferrotype. Daguerreotypes were introduced in in Paris, France, constituting for some photo-historians the beginning of photography. Ambrotypes and tintypes, made by the wet collodion process, originated in the s. Daguerreotypes continued to be made into the s. Ambrotypes were made for a little while longer. Tintypes survived into the 20th century in modified form as a type of instant portrait photograph.

In , Louis Daguerre in France and Henry Fox Talbot in England, who had been working independently, announced competing photographic discoveries. Their processes were very different, but both played major roles in the history of photography. But the daguerreotype had serious limitations. The mirror-like surface of the image could only be viewed from a narrow angle. Further, the process produced a one-of-a-kind image that did not permit printing duplicates. Talbot was the first of the early experimenters in photography to propose, in this paper, a fundamental principle of modern photography: the use of a negative image to produce an unlimited number of positive copies.

Commercial portrait photography began in the s and old family photographs can portray ancestors from the early-Victorian era onwards.

All available evidence should be considered, but often most useful for accurate photo dating are the picture clues, especially the fashions worn by their subjects: clothes, accessories and hairstyles.

Silver, mercury and gold were the elements involved in the first truly successful photographic process: the daguerreotype. At the end of the eighteenth century the observation of optical phenomena and the physical-chemical action of light on certain elements had initiated a search for techniques that could reproduce reality without any further manual intervention. Unlike conventional photographs, daguerreotypes are metallic objects: copper plates coated with a thin layer of highly polished silver that can be viewed either as negatives or positives.
The image consists of particles of a silver-mercury amalgam upon this reflective surface. Their submicron size ensures a very high optical resolution. Contemporary newspaper accounts, transcripts of academic presentations and the first technical manuals to be published feature a wide range of modifications and solutions proposed in many different countries, which effectively reveal the level of scientific knowledge prevailing from to In this period most of the initial drawbacks were successfully overcome, and these developments ensured the worldwide diffusion of the procedure.
Exposure times were reduced by the double sensitisation of the plate and its treatment with a solution of gold chloride and sodium thiosulphate increased the stability of the image a process developed by Armand-Hippolyte-Louis Fizeau in A prism was used to rectify the mirror-image inversion, and sophisticated tinting techniques pioneered by the Swiss daguerreotypist Johann Baptist Isenring were employed to amend and enhance its monochrome aspect.
By the end of the most essential technical improvements had been made, primarily in the design of lenses. In Petzval invented a conical metal camera, which recorded impressions on circular plates. When the daguerreotype process came to America it was pioneered by Alexander S.

This primitive method captured images onto small silver-coated copper plates, producing just one permanent, irreproducible print. Already in November of , an agent arrived in New York City to sell equipment for producing daguerreotypes. Within a few years nearly every city and small town had a photography studio, and rich and poor alike flocked to sit for their portrait. Exposure times for early photographic processes were quite long, and portraits often contain blurred images of sitters moving a head or an arm.

One of the most available, most misunderstood and certainly the most misidentified of all antiques are photographs. It would be difficult to find an antique dealer who has not at one time or another bought and sold 19th century photographs, yet, the average dealer would be hard pressed to correctly identify or date the different types of photographic images they routinely encounter.
This exploded view of the anatomy of a photographic case shows the various levels of the image side of the case. All images courtesy Dr. Anthony J. I bought my first 19th century photograph in on a farm in Pennsylvania, out of a barn that housed ducks and doubled as an antique shop. I was fascinated by the idea that antique images were a small window into the past; I have collected photographs ever since. To fund this newly acquired habit I would scour our New York City neighborhood with my red wagon and collect discarded furniture, glassware, artwork, and textiles, which I sold on the weekends at the 26th Street Flea Market in Manhattan.
I used the profits to subsidize my photograph collecting and purchased photographs each week from other dealers at the flea market who routinely saved images for me beneath their tables; I was the photograph boy. Soon I was buying photographs at auctions where they were usually sold as box lots with often more than one-hundred in a lot; the Pine Bush Grange Hall was my favorite source.
I soon learned to identify daguerreotypes, ambrotypes, tintypes ferrotype, melainotype, melanotype , cartes de visite carte-de-visite, CDV, CdV , cabinet cards, cyanotypes, and real-photo postcards and drove my family crazy with frequent testing. Though there are other types of photographs, these are the examples most frequently encountered in the antique trade.
In short, daguerreotypes are photos on highly polished, silver-plated, copper sheets where the exposed photographic plate becomes the one-of-a-kind image unlike glass negatives and later celluloid innovations where the image is printed from a negative and could be duplicated.
