In general, black-and-white prints using either silver or carbon-based media may last longer than some colour prints. Some black-and-white prints are produced using ink-jet printers, or colour photographic paper using the RA 4 process.
Silver mirroring, or "silvering", is a degradation process of old black-and white-photographic prints caused by conversion of the black silver oxide to silver metal. This results in a slightly bluish, reflective patch in the darkest part of a print or negative when examined in raking light. It often indicates improper storage of the prints. [3]
The gelatin silver process is the most commonly used chemical process in black-and-white photography, and is the fundamental chemical process for modern analog color photography. As such, films and printing papers available for analog photography rarely rely on any other chemical process to record an image.
The majority of monochrome photographs produced today are black-and-white, either from a gelatin silver process, or as digital photography. Other hues besides grey can be used to create monochrome photography, [1] but brown and sepia tones are the result of older processes like the albumen print, and cyan tones are the product of cyanotype prints.
Adox was a German camera and film brand of Fotowerke Dr. C. Schleussner GmbH of Frankfurt am Main, the world's first photographic materials manufacturer. In the 1950s it launched its revolutionary thin layer sharp black and white kb 14 and 17 films, referred to by US distributors as the 'German wonder film'. [1]
Advertisement for Ansco Cyko photographic paper, 1922. Photographic paper is a paper coated with a light-sensitive chemical, used for making photographic prints.When photographic paper is exposed to light, it captures a latent image that is then developed to form a visible image; with most papers the image density from exposure can be sufficient to not require further development, aside from ...
In the traditional photochemical post-production workflow, release prints are usually copies, made using a high-speed continuous contact optical printer, [5] of an internegative (sometimes referred to as a 'dupe negative'), which in turn is a copy of an interpositive (these were sometimes referred to as 'lavender prints' in the past, due to the slightly colored base of the otherwise black-and ...
Monochrome prints, usually black-and-white, but they may be sepia, cyan or any other preferred color. Duochrome (duotone) prints, an effect many printers are familiar with, using complementary or associated colors to their best effect. Trichrome prints, traditional full-color prints made by layering YMC (yellow, magenta and cyan) pigment sheets.
