Note: this photo is a photochrom, which is "a process for producing colorized images from a single black-and-white photographic negative via the direct photographic transfer of the negative onto lithographic printing plates. The process is a photographic variant of chromolithography (color lithography). Because no color information was preserved in the photographic process, the photographer would make detailed notes on the colors within the scene and use the notes to hand paint the negative before transferring the image through colored gels onto the printing plates."

Postcard History

Postcards, as we are familiar with them today, have taken a considerable amount of time to develop. First restricted by size, color, and other regulations, postcard production blossomed in the late 1800s and early 1900s. Postcards were popular because they were a quick and easy way for individuals to communicate with each other. Today deltiology, or the collection of postcards, is a popular hobby...

Before postcards, some people sent cards through the mail with attached postage. Because these cards are not actually postcards, they are typically referred to as “mailed cards.” During this period, envelopes were produced with pictures on them, and some speculate that postcards are the direct descendants of the picture envelopes. While we do not have picture envelopes that date from this time period, this envelope with the Smithsonian Institution Building on it is similar to the earlier picture envelopes.

On February 27, 1861, the US Congress passed an act that allowed privately printed cards, weighing one ounce or under, to be sent in the mail. That same year John P. Charlton (other places seen as Carlton) copyrighted the first postcard in America.

In 1870, Hymen L. Lipman began reissuing Charlton’s postcard under a new name: Lipman’s Postal Cards. Congress passed legislation on June 8, 1872, that approved government production of postal cards. The first government-produced postcard was issued on May 1, 1873. One side of the postcard was for a message and the other side was for the recipient’s address. By law, the government postcards were the only postcards allowed to bear the term “Postal Card.” Private publishers were still allowed to print postcards, but they were more expensive to mail than the government-produced cards (2¢ instead of 1¢)...

Modern photochrom-style postcards first appeared in 1939 when the Union Oil Company began to carry them in their western service stations. Production of the postcards slowed during World War II because of supply shortages, but after the war, they dominated the postcard market. The photochrom postcards are in color, and their images closely resemble photographs. Photochrom postcards are the ones most familiar to us today. In the 1990s the advent of e-cards and email started the decline of the postcard’s popularity. Today postcards are typically purchased as souvenirs, rather than a quick way to communicate.

These beautiful, romantic old postcards show Scotland from a time long gone.

Originally published by the Detroit Publishing Company, they were created by image-makers fascinated by Scotland’s castles and sweeping landscapes, and much of the collection gives a vivid vibe of the late 19th century.

The color effects on these pictures are created using the so-called “photochrom technique."

Photochrome was a process for producing colorized images from black-and-white photographic negatives via the direct photographic transfer of a negative onto lithographic printing plates.

The process was invented in the 1880s and was most popular in the 1890s.

The result is a cross between a photograph and a painting that depicts famous Scottish towns, landscapes, and buildings in a unique way.

Scotland was already one of the most urbanized societies in Europe by 1800.

The industrial belt ran across the country from southwest to northeast.

By 1900, the four industrialized counties of Lanarkshire, Renfrewshire, Dunbartonshire and Ayrshire contained 44 percent of the population.

Glasgow and the River Clyde became a major shipbuilding center.

Glasgow became one of the largest cities in the world and nicknamed the "Second City of the Empire” after London.

The industrial developments, while they brought work and wealth, were so rapid that housing, urban planning and provision for public health did not keep pace with them.

For quite a time, the living conditions in some of the small towns and cities were notoriously bad, with overcrowding, high infant mortality, growing rates of tuberculosis and industrial pollution.

The Detroit Photographic Company9 was launched as a photographic publishing firm in the late 1890s by Detroit businessman and publisher William A. Livingstone, Jr., and photographer and photo-publisher Edwin H. Husher.

They obtained exclusive rights to use the Swiss “Photochrom” process for converting black-and-white photographs into color images and printing them by photolithography.

This innovative process was applied to the mass production of color postcards, prints and albums for sale to the American market.

The firm became the Detroit Publishing Company in 1905.

The color photographs of Scotland collected in this article are part of a wider archive of historic “photochrom” pictures bought by the Library of Congress.

Vivid photochromes of Tyrol, 1890 

These amazing postcards depict the Princely County of Tyrol, an mountainous region of the Austro-Hungarian empire. The pictures were created using the Photochrom process, a revolutionary procedure that consists of producing ink-based images through the direct photographic transfer of an original negative onto litho and chromographic printing plates.

Hans Jakob Schmid (1856-1924), who worked for the Swiss firm Orell Füssli, invented the technique in the 1880s. The prints look deceptively like color photographs. But when viewed with a magnifying glass the small dots that comprise the ink-based photomechanical image are visible.

The photomechanical process permitted mass production of the vivid color prints. Each color in the final print required a separate asphalt-coated lithographic stone, usually a minimum of six stones and often more than ten stones.

Tyrol is a historical region in the Alps—in Northern Italy and western Austria. The area was historically the core of the County of Tyrol, part of the Holy Roman Empire, Austrian Empire and Austria-Hungary, from its formation in the 12th century until 1919.

Pulpit terrace print This is a really neat image. This is Pulpit Terrace, part of Yellowstone’s Mammoth Hot Springs named because it looks so much like a preacher’s pulpit from the side that you can find old photographs of people standing behind it and looking like they’re preaching (see our twitter page below). This image shows it as it appeared in 1898, but it’s not a photograph.

This is a photomechanical print, a printing of an area based on a photographic negative. The color in the shot may reflect a bit of artistic expression, but this is still a pretty neat, color look at how a terrace in Yellowstone could have appeared before the advent of color photography, and what the rocks of Mammoth Hot Springs looked like before large numbers of visitors affected the landscape. -JBB Image credit: Photochrom Co/Library of Congress http://www.loc.gov/item/2008678251/ More: https://twitter.com/TheEarthStory/status/639507092487958528
