In most instances, the image is varnished and placed in a case for safe-keeping. Known examples of ambrotypes printed on yellow or blue glass supports exist, but the occurrence is rare. Historical Facts Invented: In , Frederick Scott Archer presented the wet plate collodion technique to the photographic societies. Patented: Although earlier practitioners were producing precursors to the ambrotype, i.

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.

Among the first photographs to be made by Japanese photographers exclusively for Japanese clients, ambrotypes—collodion negatives exposed on blackened glass to make them look like positive images—were produced in large numbers in Japan in the s and s, well after the process had been superseded in the West. In many ways these unique combinations of photography and calligraphy exemplify the tensions of the Meiji era, a time when Japan was seeking to reconcile its own traditions with the ways of the West, including the widening influence of photography itself.

An early example shows a samurai in Western dress holding his sword, already an incongruous image. Dated to , the image was thus made at made at the end of the Edo shogunate—a time of great social upheaval, when Japan began to make its transition from feudal to modern society. The sitter’s new and yet discordantly foreign uniform and samurai sword indicate a personage of high rank.

After the advent of the Meiji era, the samurai caste was abolished and by sumurai were no longer allowed to wear their swords in public. This man therefore hovers on the edges of two eras, not quite belonging to either. Another ambrotype, dated on the case to precisely December 19, , shows a young man standing in traditional robes facing the camera. Beside him is a pedestal, traditionally a base for a piece of sculpture but here made to support a bowler hat, so that the hat is presented like an ethnographic object on display.

As these two examples indicate, a closer analysis of Japanese ambrotypes might offer a way to articulate the political and cultural complexities being negotiated by photographers in Japan in this period.

Ambrotypes & Tintypes

No large elevators of this size were erected prior to and for a state steeped in farming this was a game changer. In the foreground we see a large double-mast cargo ship with a large conveyor belt directly behind for loading or unloading from the elevator. On the right is a smaller cargo vessel waiting in line. Behind this we see another large building which appears to read Hiram Wheeler.

This first manifested in the s in a form known as ambrotypes. At first sight similar to a daguerreotype, the ambrotype too comes in a glass fronted case.

Antique Ambrotype Photographs

Last week I began a discussion of the oldest photographs, all of which were produced as encased images. The daguerreotype was the earliest of these: it was a positive photographic image on a copper plate, produced from to the early s, and was most popular from to The ambrotype is the second kind of photographic image that you may find in a case. Essentially this procedure involved coating a piece of glass with chemicals, putting the glass in the camera while still wet and exposing it to light in front of an image.

The resulting picture was called an ambrotype. These were negative images.

The glass plates do not bear dating marks as with the Daguerreotype plates. Early Ambrotypes had a second plate of glass sealed to the image. This process​.

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.

These direct image formats are unique, developed directly onto support material with no separate negative. Daguerreotypes and ambrotypes are often enclosed in a hinged case behind glass; tintypes were sometimes placed in thin folding cases. Consider the use of facsimiles instead. The duration of an exhibit should be determined in advance, and no item should be placed on display permanently.
