Eastman Color Positive
Eastman Color Positive (ECP) is a photographic processing system created by Kodak in the 1950s for the development of monopack color positive print for direct projection motion picture film stock. It is part of the Eastmancolor family of products sold by Kodak. ECP is not used for positive intermediate films because these are "pre-print" elements (e.g. archival or "protection" elements) and are never used for direct projection. One essential difference is the presence of an orange "mask" (i.e., effectively an orange base) on all films processed by ECN, and no "mask" (i.e., effectively a clear base) on all films processed by ECP. The original process, known as ECP-1, was used from the 1950s to the mid-1970s, and involved development at approximately 25°C for around 7–9 minutes. Later research enabled faster development and environmentally friendlier film and process (and thus quicker photo lab turnaround time). This process allowed a higher development temperature of 41.1°C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photographic Processing
Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.Karlheinz Keller et al. "Photography" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. All processes based upon the gelatin silver process are similar, regardless of the film or paper's manufacturer. Exceptional variations include instant films such as those made by Polaroid and thermally developed films. Kodachrome required Kodak's proprietary K-14 process. Kodachrome film production ceased in 2009, and K-14 processing is no longer available as of December 30, 2010. Ilfochrome materials use the dye destruction process. Deliberately using the wrong process for a film is known as cross processing. Common processes All photographic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kodak
The Eastman Kodak Company (referred to simply as Kodak ) is an American public company that produces various products related to its historic basis in analogue photography. The company is headquartered in Rochester, New York, and is incorporated in New Jersey. Kodak provides packaging, functional printing, graphic communications, and professional services for businesses around the world. Its main business segments are Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film. It is best known for photographic film products. Kodak was founded by George Eastman and Henry A. Strong on May 23, 1892. During most of the 20th century, Kodak held a dominant position in photographic film. The company's ubiquity was such that its " Kodak moment" tagline entered the common lexicon to describe a personal event that deserved to be recorded for posterity. Kodak began to struggle financially in the late 1990s, as a result of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Motion Picture Film
Color motion picture film refers both to unexposed color photographic film in a format suitable for use in a motion picture camera, and to finished motion picture film, ready for use in a projector, which bears images in color. The first color cinematography was by additive color systems such as the one patented by Edward Raymond Turner in 1899 and tested in 1902. A simplified additive system was successfully commercialized in 1909 as Kinemacolor. These early systems used black-and-white film to photograph and project two or more component images through different color filters. During 1930s the first practical subtractive color processes were introduced. These also used black-and-white film to photograph multiple color-filtered source images, but the final product was a multicolored print that did not require special projection equipment. Before 1932, when three-strip Technicolor was introduced, commercialized subtractive processes used only two color components and could repr ...

Film Stock
Film stock is an analog medium that is used for recording motion pictures or animation. It is recorded on by a movie camera, developed, edited, and projected onto a screen using a movie projector. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.Karlheinz Keller et al. "Photography" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastmancolor
Eastmancolor is a trade name used by Eastman Kodak for a number of related film and processing technologies associated with color motion picture production and referring to George Eastman, founder of Kodak. Eastmancolor, introduced in 1950, was one of the first widely successful "single-strip colour" processes, and eventually displaced the more cumbersome Technicolor. Eastmancolor was known by a variety of names such as DeLuxe Color, Warnercolor, Metrocolor, Pathécolor, Columbiacolor, and others.

Environmentally Friendlier
Environment friendly processes, or environmental-friendly processes (also referred to as eco-friendly, nature-friendly, and green), are sustainability and marketing terms referring to goods and services, laws, guidelines and policies that claim reduced, minimal, or no harm upon ecosystems or the environment. Companies use these ambiguous terms to promote goods and services, sometimes with additional, more specific certifications, such as ecolabels. Their overuse can be referred to as greenwashing.Greenwashing Fact Sheet. 22 March 2001. Retrieved 14 November 2009. frocorpwatch.org/ref> To ensure the successful meeting of Sustainable Development Goals (SDGs) companies are advised to employ environmental friendly processes in their production.

Photo Lab
A minilab is a small photographic developing and printing system or machine, as opposed to large centralized photo developing labs. Many retail stores use film or digital minilabs to provide on-site photo finishing services. With the increase in popularity of digital photography, the demand for film development has decreased. This means that the larger labs capable of processing 30,000-40,000 films a day are going out of business, and more retailers are installing minilabs. In Kodak and Agfa minilabs, films are processed using C41b chemistry and the paper is processed using RA-4. With these chemical processes, films can be ready for collection in as little as 20 minutes, depending on the machine capabilities and the operator. A typical minilab consists of two machines, a film processor and a paper printer/processor. In some installations, these two components are integrated into a single machine. In addition, some digital minilabs are also equipped with photo-ordering kiosks. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
