Solarized gelatin silver print, printed before 1939. More properly it is called the Sabatier effect (first described in 1859 by H. If your father (or aunt or grandfather) had a darkroom in the basement, he was definitely shooting b&w film and making b&w prints, both of which were made on ‘gelatin silver’ materials.Ī solarized gelatin silver print is not a process per se, but a technique used while making gelatin silver prints in the darkroom.

With the ability to be mass-produced, this became the most widely distributed form of photographic film and paper, spanning the full length of the 20th century up until today.

A gelatin silver print then is simply a sheet of paper that has been coated with a very thin layer of fast drying liquid gelatin within which the light sensitive silver salts are suspended.

1937), Nebraska State Highway 2, Box Butte County, Nebraska, 1978. In the middle of the 19th century, it was determined that coating paper with a light-sensitive solution in which the activated silver salts were mixed into a ‘suspension medium’ produced a range of desirable results, including higher sensitivity to light and much sharper images. These are collectively referred to as salt prints, and they were the most prevalent form of photographic prints on paper through roughly 1860. Waxing the paper negative would make it even more translucent, and gives a more sharply focused photograph. These ‘paper negatives’ can then be reversed through contact printing to yield a positive image. And thus a ‘negative’ image, a reversal of tones is produced. Areas of the image receiving the most light darken dramatically, while the darkest areas of a scene, such as those in deep shadow, will remain paper-white. The chemical bond between the salt solution and the silver nitrate yields a light-sensitive coating, which will darken when exposed to light. The most basic aspects of the procedure are as follows: sheets of paper - the thinner the better - are soaked in a weak solution of sodium chloride (ordinary table salt) after drying, the paper is then coated with a solution of silver nitrate. The principles of the former were established by the English inventor and aristocrat William Henry Fox Talbot in the 1830s.

We hope it will serve as an introduction to the vast variety you will encounter whether as a new or seasoned collector and aficionado.Īn initial basic distinction between photographic processes is a categorical one: photographs are either the result of a negative-positive process, or they are somehow made as a direct positive (positive-to-positive) process.įelix Teynard (1817-1892), Colossal Statues Seen from Three-Quarters View, the Temple of Rameses at Abu Simbel, c.1851-52. This quick guide outlines only a handful of the fascinating photographic processes that exist. Scores of distinct photographic processes have been invented the past 175 years, with innumerable men and women making important contributions. The history of photography, seen through a certain lens, is a history of scientific discoveries and technological advancements mirroring the growth of humanity’s collective progress over the course of the Industrial Revolution.
