Manufacture industrial cinema, photo and magnetic materials

A magnet is a material that can exert a noticeable force on other materials without actually contacting them. This force is known as a magnetic force and may either attract or repel. While all known materials exert some sort of magnetic force, it is so small in most materials that it is not readily noticeable. With other materials, the magnetic force is much larger, and these are referred to as magnets. The Earth itself is a huge magnet. Some magnets, known as permanent magnets, exert a force on objects without any outside influence.

Since the earliest days of cinema, film has been a colorful medium and art form. More than film color processes have been devised in the course of film history, often in close connection with photography. In this regard, both media institutionalized numerous techniques such as hand and stencil coloring as well as printing and halftone processes.

Apart from these fundamental connections in terms of the technology of color processes, film and photography also share and exchange color attributions and aesthetics. This publication highlights material aspects of color in photography and film, while also investigating the relationship of historical film colors and present-day photography.

Works of contemporary photographers and artists who reflect on technological and culture-theoretical aspects of the material of color underline these relations. Thematic clusters focus on aesthetic and technological parallels, including fashion and identity, abstraction and experiment, politics, exoticism, and travel.

Color Mania contains a general introduction to color in film and photography technique, materiality, aesthetics as well as a series of short essays that take a closer look at specific aspects.

An extensive image section illustrates the texts and color systems and continues the aesthetic experience of the various processes and objects in book form. The publication is also available in German. This database was created in and has been developed and curated by Barbara Flueckiger , professor at the Department of Film Studies, University of Zurich to provide comprehensive information about historical film color processes invented since the end of the 19th century including specific still photography color technologies that were their conceptual predecessors.

In the University of Zurich and the Swiss National Science Foundation awarded additional funding for the elaboration of this web resource. In addition, the Institute for the Performing Arts and Film, Zurich University of the Arts provided a major contribution to the development of the database. Many further persons and institutions have supported the project, see acknowledgements. All the members of the two research projects on film colors, both led by Barbara Flueckiger, have been capturing photographs of historical film prints since Please report errors or suggestions.

Type "process: [process name]" to search for processes. Type "inventor: [inventor name]" to search for inventors. Films of this class are known as Multilayer, Monopack or Integral Tripack. Three types of Eastman Colour Film are manufactured. These are the Colour Negative Film, intended for use as the picture negative material in the camera; the Colour lnternegative Film, used for a similar purpose to black-and-white duplicating negative film; and Colour Print Film, which may be employed in preparing prints from either the Colour Negative or Colour lnternegative.

A special black-and-white Separation Positive Film is also provided and this is intended for use in preparing three separation positives from the Colour Negative.

The separation positives form an intermediate link with the Colour Negative when making a Colour Internegative, so that their function is similar to that of a master positive in a black-and-white system.

Integral tripack camera films have the advantage that they may be used in a standard black-and-white camera, and apart from a check on the colour correction and focus of the lens, no special precautions are necessary. It is of interest to note that the colours of integral tripack negatives, as well as the densities, are reversed compared with the original scene. The coloured images in Eastman Colour Films are produced by a method known as dye-coupling development.

For this a special developing agent is used in conjunction with a second compound known as the colourforming coupler.

Photographic development is a process of chemical reduction brought about by the developing agent, which is oxidized in proportion to the amount of silver formed. The oxidized developing agent combines with the colour forming coupler to create a dye of appropriate colour, the concentration of which is proportional to the amount of silver in the image. The dye thus formed must be insoluble in water so that the reaction shall be quite local and a dye image of high resolution obtained.

The silver image is removed at a later stage of the process. Three colour-forming couplers provide the appropriate dyes and are incorporated in the relevant emulsion layers. Craig, G.

If it's something film-related, we probably have it. Using film processing equipment requires carefully applied chemicals in a controlled environment such as a darkroom to help protect the film from overexposure.

There are several processes for making magnets, but the most common method is called Powder Metallurgy. Therefore, these magnets are most often called sintered magnets. Unlike ferrite, which is a ceramic material, all of the rare earth magnets are metal alloys. Suitable raw materials are melted under vacuum or inert gas in an induction melting furnace.

Sensors for industrial machines are used to detect a variety of process signals for a given application. A few examples of process signals are, material color, pressures, flow, fluid levels, temperature, and human presence. The most common type of sensors are: Proximity Sensor: Used to detect an object without physically contacting the object. Flow Sensor: Similar to pressure sensors. Detects the presence or absence of flow. Level Sensor: Allows for process control based on the level in a vessel. Consider a tank which must remain full.

Magnet Controller. Rubber and ceramic magnets are ideal for smaller projects.

Videotape is an integral component of the video technology that has profoundly impacted the media and home entertainment industries. First controlled by the television industry, videotape and video technology are now widely available to the private sector and have led to significant changes in the way that information is distributed and entertainment is created. Videotape is all about magnetic recording.

CinemaScope is an anamorphic lens series used, from to , and less often later, for shooting widescreen movies that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter. Its creation in by Spyros P.

To understand magnetism, it is essential to identify what types of materials are used to create magnets and how the materials used affect the ultimate performance of a magnet. These are the same materials that can be magnetised to create permanent magnets, Here you can see a list of magnetic elements and minerals:. Magnetic materials are categorised as magnetically hard, or magnetically soft materials. Magnetically soft materials are easily magnetised but the induced magnetism is usually temporary. For example, if you rub a permanent magnet along a nail, or a screwdriver, the nail or screwdriver will become temporarily magnetised and will emit their own weak magnetic field. This is because a large number of their iron atoms are temporarily aligned in the same direction by the external magnetic field. Like magnetically soft materials, magnetically hard materials can be magnetised by a strong external magnetic field, such as those generated by an electromagnet. The difference being that magnetically hard materials will remain magnetised indefinitely, unless they are demagnetised by an opposing magnetic field, raised above their curie temperature or allowed to corrode. Magnetically hard materials are used to create permanent magnets made from alloys generally consisting of varying amounts of iron, aluminium, nickel, cobalt and rare earth elements samarium, dysprosium and neodymium. The strongest permanent magnets are known as neodymium magnets and are made from an alloy of neodymium, iron and boron. Because all materials have a different atomic structure different materials react differently when placed in a magnetic field.

A worldwide material shortage is delaying cassette production

Just when cassette tapes appeared to be making a comeback, a worldwide shortage of gamma ferric oxide has slowed production. National Audio Company NAC , the largest cassette tape manufacturer in the US, sent a letter to its customers explaining that, due to the shortage, it is unable to fill orders on its usual day schedule. Instead, it's working as fast as the raw material arrives. If you weren't racing out to buy the Stranger Things soundtrack on cassette , you might not have realized that cassette sales are growing. In , sales jumped a whopping 74 percent , and they've continued to climb. In , sales increased another 23 percent, reaching a total of , tapes , compared to 74, in Apparently, there's only one factory refining gamma ferric oxide, an essential ingredient used to make the magnetic recording tape. According to NAC, that facility has been "under renovation" for most of the year, and NAC is waiting on 50 tons of back-ordered gamma ferric oxide.

Digital cinema

Whereas film reels have to be shipped to movie theaters , a digital movie can be distributed to cinemas in a number of ways: over the Internet or dedicated satellite links, or by sending hard drives or optical discs such as Blu-ray discs. Digital movies are projected using a digital video projector instead of a film projector. Digital cinema is distinct from high-definition television and does not necessarily use traditional television or other traditional high-definition video standards, aspect ratios, or frame rates. As digital-cinema technology improved in the early s, most theaters across the world converted to digital video projection. The transition from film to digital video was preceded by cinema's transition from analog to digital audio , with the release of the Dolby Digital AC-3 audio coding standard in Princen, A. Johnson and Alan B. Bradley at the University of Surrey in , [5] and then Dolby Laboratories adapted the MDCT algorithm along with perceptual coding principles to develop the AC-3 audio format for cinema needs.
