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 majority of the ambrotypes and tintypes are portraits by Contributor: Brady’s National Photographic Portrait Galleries; Date:
Ambrotypes are one-of-a-kind photographs on glass plates. They are still being made by hand using the collodion process dating back to the s. The black-and-tan picture is as permanent as a photograph can be; originals from the s can be found in any antique shop. This workshop is a great opportunity to get a feel of what it was like to sit in front of a camera between the s and s. Everyone will have the opportunity to learn hands-on how to pour the liquid collodion solution onto a glass plate and will participate in elements of processing the plates in the darkroom.
Notes: We suggest you wear dark colors rather than light colors, as they photograph better with this process. Audience: Limited to 8 participants, this 1-day workshop is a fun way to learn the ambrotype process. No experience necessary.
Daguerreotypes, Ambrotypes, and Tintypes
One thing I found useful is the archival plastic sleeves used for post cards. They come in at least two basic sizes. You can slide the ambrotype case into one and either affix an identifying tag or write on the sleeve itself.
AMBROTYPE ( to the end of the Civil War)The ambrotype is a thin negative image on glass made to appear as a positive by showing it against a black.
Like a print on paper, it is viewed by reflected light. Like the daguerreotype , which it replaced, and like the prints produced by a Polaroid camera , each is a unique original that could only be duplicated by using a camera to copy it. The ambrotype was introduced in the s. During the s it was superseded by the tintype , a similar photograph on thin black-lacquered iron, hard to distinguish from an ambrotype if under glass. One side of a clean glass plate was coated with a thin layer of iodized collodion , then dipped in a silver nitrate solution.
The plate was exposed in the camera while still wet. Exposure times varied from five to sixty seconds or more depending on the brightness of the lighting and the speed of the camera lens. The plate was then developed and fixed. The resulting negative , when viewed by reflected light against a black background, appears to be a positive image: the clear areas look black, and the exposed, opaque areas appear relatively light.
This effect was integrated by backing the plate with black velvet; by taking the picture on a plate made of dark reddish-colored glass the result was called a ruby ambrotype ; or by coating one side of the plate with black varnish. Either the emulsion side or the bare side could be coated: if the bare side was blackened, the thickness of the glass added a sense of depth to the image.
In either case, another plate of glass was put over the fragile emulsion side to protect it, and the whole was mounted in a metal frame and kept in a protective case. In some instances the protective glass was cemented directly to the emulsion, generally with a balsam resin. This protected the image well but tended to darken it.

In this week’s post about dating your photographs, Colin Harding shows you how to identify a collodion positive, also known as an ambrotype.
Share This Page. Thread Tools. Mar 5, 1. Messages: 3. Hey Guys, This is my first post. I work for a non-profit organization that funds an addiction therapy program. We accept donations as a means of funding and someone donated an ellaborately designed ambrotype. The photo is about 2″ by 2. Im trying to get a little more information on the dating and origin of the piece for description. I know there are countless variables to be assesed in these types of photos and you guys seem pretty knowledgeable!
Thank you for any help! Mar 5, 2. Messages: 10,
Ambrotype (Positive Collodion)
Early photos were the Daguerreotype, the Ambrotype, the Carte de Visite, Cabinet photos, and postcards. The Daguerreotype from used a metal plate, producing a reversed and positive image. The Ambrotype ‘s – mid ‘s was a negative image on a glass plate, also reversed. The image when viewed against a black background appeared as a positive.
In the ‘s the photos had squared corners. In the ‘s the photos had coloured borders, whilst in the ‘s the photos had rounded corners.
