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. Most items should not be displayed for longer than 3 to 4 months, assuming other conditions such as light levels, temperature, and relative humidity are within acceptable ranges. Facsimiles or items of low artifactual value may be exhibited for longer periods of time. Between display periods it should be returned to an appropriate environment where it may “rest” in dark storage. Light levels should be kept as low as possible. When on display, objects should be protected from exposure to natural light, which contains high levels of UV radiation.

Naturally, the mats and cases containing daguerreotypes provide plenty of information and clues to help date the pieces. Unfortunately, both items are easily substituted and some of the changes made are purposefully deceptive. Never judge the period of an image or its relative value simply by casual observation. Let me say strongly, right now, that I don’t want the majority of you folks who will read this to start prying every daguerreotype you find out of the case and taking apart the glass, mat and plate.

That would be sheer madness and might severely damage the piece. If you aren’t prepared to reglass and archivally reseal the entire package, then please don’t disassemble it. Please remember that all the physical information is derived from my direct observations, and while there are definitely some anomalies, this information is usually quite correct. By my own definition, very early daguerreotypes date from to the end of During this period, the processes required to attain any results were widely disseminated and discussed.

However, many refinements of the art were closely guarded secrets, especially after the artists and scientists had accomplished their experiments in producing portraits. Once the entrepreneurs who successfully operated the first commercial daguerreian studios began charging a fee for each faint, steely gray apparition on the mirrored surfaces, the competition began in earnest.

Americans were initially suspicious about the accounts of the daguerreotype that reached their shores on the steamship “Great Western”, September 10, However, Samuel F.

Jan 25, – Woman. Date: between and Daguerreotype. Case cover material: leather, full case. Photographer unidentified.

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.

The daguerreotype was a positive-only process allowing no reproduction of the picture. Preparation of the plate prior to image exposure resulted in the formation of a layer of photo-sensitive silver halide, and exposure to a scene or image through a focusing lens formed a latent image. The latent image was made visible, or “developed”, by placing the exposed plate over a slightly heated about 75C cup of mercury. The mercury vapour condensed on those places where the exposure light was most intense, in proportion with the areas of highest density in the image.

This produced a picture in an amalgam, the mercury vapour attaching itself to the altered silver iodide. Removal of the mercury image by heat validates this chemistry. The developing box was constructed to allow inspection of the image through a yellow glass window while it was being developed. The image produced by this method is so delicate it will not bear the slightest handling. Practically all daguerreotypes are protected from accidental damage by a glass-fronted case.

It was discovered by experiment that treating the plate with heated gold chloride both tones and strengthens the image, although it remains quite delicate and requires a well-sealed case to protect against touch as well as oxidation of the fine silver deposits forming the blacks in the image. The best-preserved daguerreotypes dating from the nineteenth century are sealed in robust glass cases evacuated of air and filled with a chemically inert gas, typically nitrogen.

Its subject though, remains much younger…she could easily pass in looks and age for my youngest daughter at fourteen…but is certainly not yet in her twenties. She is wearing a carefully fitted, layered and pleated black crepe mourning dress with tiered sleeves and wasp waist. Her sad expression is in keeping, but its accompanying bewilderment conveys an emotion deeply felt, so perhaps the deceased was a close relative.

Her hands hold each other in a defensive gesture and like her cheeks, they are tinted pink; looking at them, rendered at a mere centimetre on the sixth-plate 7cm x 8.
