A chloro-bromide print is a type of silver gelatin print known for its deep rich blacks and crisp whites, often produced on high gloss paper. This printing method combines the properties of both silver bromide and silver chloride, resulting in a warmer brownish-black tone compared to prints made solely with silver bromides or silver chlorides. Chloro-bromide prints are appreciated for their excellent archival properties, ensuring the longevity and preservation of the image.
Silver Salts Silver salts are light-sensitive chemical compounds used in photography. When exposed to light—either in a camera (for film and negatives) or in the darkroom (for photographic papers)—the silver salts darken in proportion to the amount of light reflected from the subject, creating an image. Silver Bromide Print Silver bromide prints are a type…
Archival properties refer to the durability and longevity of photographic paper and prints, indicating how resistant they are to fading and degradation over time. Various factors affect archival quality, including exposure to UV (ultraviolet) light, humidity, temperature, pollution, and acidity. To enhance archival properties and ensure the preservation of photographic prints, it is important to…
Dye-based inks are composed of dyes that dissolve completely in solution, unlike pigment-based inks, which contain tiny particles suspended in the liquid. This characteristic allows dye-based inks to be fully absorbed into the paper, creating an image that is essentially a highly controlled stain. The resulting images are smooth and even, offering a vast range…
A digital interneg is an internegative produced through digital methods rather than traditional photographic techniques. The process involves scanning an original negative or its positive image to create a digital file. This digital file is then used to produce a new negative via laser writing. Digital internegs allow for precise control and manipulation of the…
The autochrome is an early color photography process patented on December 17, 1903, by Auguste and Louis Lumière. Before its commercialization in 1907, the Lumière brothers shared the autochrome technique with select photographers, such as Sergey Prokudin-Gorsky. The process was widely used from 1907 until about 1932, notably for many photographs of the First World…
Polaroid is a well-known manufacturer and trademark of a photographic system that produces ‘instant’ prints. This system combines film, paper, and developing solution into a single unit. When the film/paper is exposed to light, the image begins to develop immediately, fully forming within a maximum of 5 minutes. To ensure optimal results and prevent over-developing,…
