The sizes quoted above for half-plate and quarter-plate are a little different from ‘normal’ glass plate sizes. I don’t know why. Half-plate and whole plate sizes for glass plates are the appropriate proportions of whole-plate. Large I have also received an email from a collector in London who has a photograph of a young girl with dress, ear rings and rings painted over the original photo. It is a tintype measuring 13 ins x 10 ins. Cabinet Prints Portraits In the 19th century, studio portraits were usually produced as either cartes de visite the smaller size or cabinet prints the larger size.
C Stamp Square from to Many Stamp Squares are just words or plain shapes. Each photographer would have bought his Postcard photographic paper from a supplier.

Studio set at Blists Hill Museum. Part of the camera back revolved rather like that of a Mamiya RB67 enabling portrait or landscape format. Having focused on the subject with a brass wheel and rack arrangement the Teak plate holder would be inserted into wooden grooves in the camera back which would then push the focussing screen further along the grooves. The plate holder had then taken the place of the screen and you would be ready to take your first photograph having pulled out the dark slide.
One plate holder was big enough to take three exposures by moving the plate holder further along the grooves each time though taking three exposures of one sitter would be frowned upon by the branch manager and, if it occurred too often, might be reported to the Regional? Head Office in Wolverhampton. The orthochromatic paper ‘film’ that the plate holder contained supplied by Kodak when Geoff was working for Jerome would be 9X4 inches an estimate and the paper was much more sensitive to light than Bromide printing paper.
Members of the Stead family, whose father founded ‘ Gratispool ‘, believe Gratispool received its paper ‘film’ from an organisation called ‘Criterion’ prior to World War 2, but received supplies from Kodak post This was operated by an actual bicycle back brake cable attached to a brass release that operated in the same way as a bicycle brake. When you squeezed it together the flap would open towards the top of the bellows and then close quickly with the aid of a spring on releasing.
Other Jerome photographers preferred to remain behind the camera whenever possible, but I preferred the ‘up close’ position, even for passports. Three prints would have been supplied.
A stamp can be one of the most significant parts of a photograph. The stamping can help tell us much, who was the photographer, the company the photo was made for magazine, Associated Press , why and when it was made. Sometimes a stamp will tell us the age of the photo. While a stamp or tag does not in and of itself authenticate a photo stamps are rarely forged , it helps the collector in making a judgment.

Beginning of modern portrait photography Cabinet Card was the Most Common Family Portrait The cabinet card was made by using the same steps for creating CDVs, still exhibiting the sepia look. However, the cabinet card’s image area was more than double the CDV. It was introduced in the late s in England, but did not gain much attention in the U. While it was a bigger image than the CDV, it did not offer much of a quality difference until the mid s. That is when the effect of new photographic papers and camera improvements really became apparent.
Many cabinet card photographs from the s and s are exquisite pieces of artwork, exhibiting technical excellence and wonderful composition.

Their processes were very different, but both played major roles in the history of photography. 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: That same year, Daguerre announced the daguerreotype photographic process.
Two years later, however, in , Talbot announced the invention of the calotype, a marked improvement on the process. William Henry Fox Talbot, Calotype images lacked fine detail, however, making the process unsuitable for portraits. The daguerreotype remained the dominant form, and as a result early American photographic portraits on paper are extremely rare.
Like the majority of painters of the late nineteenth century, Homer never spoke directly about photography, nor did he ever exhibit such images in any formal manner. As one attuned to appearances and constantly experimenting with how to represent them, Homer understood that photography as a new technology of sight had much to reveal.
Though he privileged his own vision and saw painting as the most compelling means to figure the world, he grew to learn that photography—despite its limitations and problematic reputation in the world of the fine arts—was a medium that did not undermine, but instead complemented his larger artistic interests. But a little-studied set of photographs of the waxes that were taken just a few short months after Degas died offers us a richer and clearer understanding of his sculptural practice and sheds crucial light on certain important but overlooked transformations that these works underwent before they were cast.
Post Card History and Dating Methods. Although the world’s first picture post cards date from the s to the mids, post cards, as we know them, came into being in the United States about
The exception here is among private-sector nonunion women who have a high school diploma or less education. For this group, annual median wages for much of the past decades have been relatively flat. And by , women with only a high school diploma or less education had seen their wages drop below levels that prevailed in Yet these explanations ignore a vital contributing factor: Unions and their effects on wage trends have been studied, but the research focuses on how the shrinking number of private-sector union members reduces the wage gains that accompany membership.
Officially the private-sector unionization rate is 6. The erosion was even larger among men without a college degree, falling from 38 percent to 11 percent. Union membership was not as high among private-sector women as men in , just 16 percent, so the drop by to 6 percent was not as severe the fall among non—college graduate women was the same.

Daguerreotypes The daguerreotype was created by Louis Jacques Mande Daguerre and is known by photography experts as the first practical form of photography.
Daguerreotypes were produced on a thin copper metal support that had a polished coating of silver that was mirror-like. In America, daguerreotypes were often placed in hinged, wooden cases with paper or leather coverings. Also look for their highly-polished silver support. Salt printing was also the first process to utilize both a negative and a positive allowing photographers to create prints of larger quantities.
You’ll also gain access to the MyHeritage discoveries tool that locates information about your ancestors automatically when you upload or create a tree. What will you discover about your family’s past? Photographers would coat a thin sheet of paper with egg white which would hold light-sensitive silver salt on the surface of the paper, preventing image fading.

Boxes that resemble a decorative bound book were also available to store large sets of images. Printed on thin paper with blank backs, photochrom sizes ranged widely. Most prints are 6. Large mammoth plate photochroms [ view samples ] and panoramic photochroms [ view samples ] were also produced. At a time when color photography was still rare, demand for these color images was high.
The Detroit Photographic Company reportedly produced seven million photochrom prints in some years.

Sunday, March 18, Dating Old Photographs: Example 2 Crayon Enlargement This is one I found in an antique store recently. It is actually a crayon enlargement, which was an enlarged copy made of a cabinet card or carte de visite. The trouble with enlargements of such photos was that the results often weren’t very clear, so the artist or photographer would then enhance it by drawing over it with other materials like charcoal or pastels. Sometimes, such as in this case, it would be colorized, but that was not always the case, there are many black and white crayon enlargements.
Either way, the effect of the enhancement typically makes the image look almost more like a drawing or painting than a photograph, but at the same time, certain elements appear too realistic to not be a photograph. That’s because it’s basically both. Known date of colorized enlargement: Estimated date of original photograph: I didn’t purchase this one and didn’t have a measuring tape with me, but it was probably something like 11×14, though they can be even larger.
