Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. It has been defined both as "the Science of Justice" and "the Art of Justice". Law is a system that regulates and ensures that individuals or a community adhere to the will of the state. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent in common law jurisdictions. Private individuals can create binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process; the formation of laws themselves may be influenced by a constitution, written or tacit, the rights encoded therein. The law shapes politics, economics and society in various ways and serves as a mediator of relations between people. A general distinction can be made between civil law jurisdictions, in which a legislature or other central body codifies and consolidates their laws, common law systems, where judge-made precedent is accepted as binding law.
Religious laws played a significant role in settling of secular matters, is still used in some religious communities. Islamic Sharia law is the world's most used religious law, is used as the primary legal system in some countries, such as Iran and Saudi Arabia; the adjudication of the law is divided into two main areas. Criminal law deals with conduct, considered harmful to social order and in which the guilty party may be imprisoned or fined. Civil law deals with the resolution of lawsuits between individuals and/or organizations. Law provides a source of scholarly inquiry into legal history, economic analysis and sociology. Law raises important and complex issues concerning equality and justice. Numerous definitions of law have been put forward over the centuries; the Third New International Dictionary from Merriam-Webster defines law as: "Law is a binding custom or practice of a community. The Dictionary of the History of Ideas published by Scribner's in 1973 defined the concept of law accordingly as: "A legal system is the most explicit, institutionalized, complex mode of regulating human conduct.
At the same time, it plays only one part in the congeries of rules which influence behavior, for social and moral rules of a less institutionalized kind are of great importance." There have been several attempts to produce "a universally acceptable definition of law". In 1972, one source indicated. McCoubrey and White said that the question "what is law?" has no simple answer. Glanville Williams said that the meaning of the word "law" depends on the context in which that word is used, he said that, for example, "early customary law" and "municipal law" were contexts where the word "law" had two different and irreconcilable meanings. Thurman Arnold said that it is obvious that it is impossible to define the word "law" and that it is equally obvious that the struggle to define that word should not be abandoned, it is possible to take the view that there is no need to define the word "law". The history of law links to the development of civilization. Ancient Egyptian law, dating as far back as 3000 BC, contained a civil code, broken into twelve books.
It was based on the concept of Ma'at, characterised by tradition, rhetorical speech, social equality and impartiality. By the 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code, which consisted of casuistic statements. Around 1760 BC, King Hammurabi further developed Babylonian law, by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae, for the entire public to see; the most intact copy of these stelae was discovered in the 19th century by British Assyriologists, has since been transliterated and translated into various languages, including English, Italian and French. The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society; the small Greek city-state, ancient Athens, from about the 8th century BC was the first society to be based on broad inclusion of its citizenry, excluding women and the slave class. However, Athens had no legal science or single word for "law", relying instead on the three-way distinction between divine law, human decree and custom.
Yet Ancient Greek law contained major constitutional innovations in the development of democracy. Roman law was influenced by Greek philosophy, but its detailed rules were developed by professional jurists and were sophisticated. Over the centuries between the rise and decline of the Roman Empire, law was adapted to cope with the changing social situations and underwent major codification under Theodosius II and Justinian I. Although codes were replaced by custom and case law during the Dark Ages, Roman law was rediscovered around the 11th century when medieval legal scholars began to research Roman codes and adapt their concepts. Latin legal maxims were compiled for guidance. In medieval England, royal
Copyright is a legal right, existing in many countries, that grants the creator of an original work exclusive rights to determine whether, under what conditions, this original work may be used by others. This is only for a limited time. Copyright is one of two types of intellectual property rights, the other is industrial property rights; the exclusive rights are not absolute but limited by limitations and exceptions to copyright law, including fair use. A major limitation on copyright on ideas is that copyright protects only the original expression of ideas, not the underlying ideas themselves. Copyright is applicable to certain forms of creative work. Some, but not all jurisdictions require "fixing" copyrighted works in a tangible form, it is shared among multiple authors, each of whom holds a set of rights to use or license the work, who are referred to as rights holders. These rights include reproduction, control over derivative works, public performance, moral rights such as attribution. Copyrights can be granted by public law and are in that case considered "territorial rights".
This means that copyrights granted by the law of a certain state, do not extend beyond the territory of that specific jurisdiction. Copyrights of this type vary by country; the public law duration of a copyright expires 50 to 100 years after the creator dies, depending on the jurisdiction. Some countries require certain copyright formalities to establishing copyright, others recognize copyright in any completed work, without formal registration. Copyright is enforced as a civil matter, though some jurisdictions do apply criminal sanctions. Most jurisdictions recognize copyright limitations, allowing "fair" exceptions to the creator's exclusivity of copyright and giving users certain rights; the development of digital media and computer network technologies have prompted reinterpretation of these exceptions, introduced new difficulties in enforcing copyright, inspired additional challenges to the philosophical basis of copyright law. Businesses with great economic dependence upon copyright, such as those in the music business, have advocated the extension and expansion of copyright and sought additional legal and technological enforcement.
Copyright licenses can be granted by those deputized by the original claimant, private companies may request this as a condition of doing business with them. Services of internet platform providers like YouTube, GitHub, DropBox, WhatsApp or Twitter only can be used when users grant the platform provider beforehand the right to co-use all uploaded content, including all material exchanged per email, chat or cloud-storage; these copyrights only apply for the firm that operates such a platform, no matter in what jurisdiction the platform-services are being offered. Private companies in general do not recognize exceptions or give users more rights than the right to use the platform according certain rules. Copyright came about with wider literacy; as a legal concept, its origins in Britain were from a reaction to printers' monopolies at the beginning of the 18th century. The English Parliament was concerned about the unregulated copying of books and passed the Licensing of the Press Act 1662, which established a register of licensed books and required a copy to be deposited with the Stationers' Company continuing the licensing of material that had long been in effect.
Copyright laws allow products of creative human activities, such as literary and artistic production, to be preferentially exploited and thus incentivized. Different cultural attitudes, social organizations, economic models and legal frameworks are seen to account for why copyright emerged in Europe and not, for example, in Asia. In the Middle Ages in Europe, there was a lack of any concept of literary property due to the general relations of production, the specific organization of literary production and the role of culture in society; the latter refers to the tendency of oral societies, such as that of Europe in the medieval period, to view knowledge as the product and expression of the collective, rather than to see it as individual property. However, with copyright laws, intellectual production comes to be seen as a product of an individual, with attendant rights; the most significant point is that patent and copyright laws support the expansion of the range of creative human activities that can be commodified.
This parallels the ways in which capitalism led to the commodification of many aspects of social life that earlier had no monetary or economic value per se. Copyright has grown from a legal concept regulating copying rights in the publishing of books and maps to one with a significant effect on nearly every modern industry, covering such items as sound recordings, photographs and architectural works. Seen as the first real copyright law, the 1709 British Statute of Anne gave the publishers rights for a fixed period, after which the copyright expired; the act alluded to individual rights of the artist. It began, "Whereas Printers and other Persons, have of late taken the Liberty of Printing... Books, other Writings, without the Consent of the Authors... to their great Detriment, too to the Ruin of them and their Families:". A right to benefit financially from the work is articulated, court rulings and legislation have recognized a right to control the work, such as ensuring that the integrity of it is preserved.
Stock photography is the supply of photographs, which are licensed for specific uses. The stock photo industry, which began to gain hold in the 1920s, has established models including traditional macrostock photography, midstock photography, microstock photography. Conventional stock agencies charge from several hundred to several thousand United States dollars per image, while microstock photography may sell for around USD 25 cents. Professional stock photographers traditionally place their images with one or more stock agencies on a contractual basis, while stock agencies may accept the high-quality photos of amateur photographers through online submission. Themes for stock photos are diverse, although Megan Garber of The Atlantic wrote in 2012 that "one of the more wacky/wondrous elements of stock photos is the manner in which, as a genre, they've developed a unifying editorial sensibility. To see a stock image is... to know you're seeing a stock image." Notable traditional stock photo agencies have included RobertStock, the Bettman Archive in New York, the Hulton Archive in the United Kingdom among many others.
In the 1990s companies such as Photodisc in Seattle, Washington began selling CD ROMs with packs of images, pioneering the royalty free licensing system at a time when rights managed licensing was the norm in the stock industry. There was a great amount of consolidation among stock photo agencies between 1990 and the mid-2000s through Corbis and Getty Images; the early microstock company iStockphoto was founded in May 2000, followed by companies such as Dreamstime, fotoLibra, Can Stock Photo and Fotolia. Newspapers and magazines were first able to reproduce photographs instead of line art in the mid-1880s with the invention of the half-tone and its use on a printing press. Starting with staff photographers independent free-lance photographers took over. One of the first examples of a stock photo was circa 1920 when American photographer H. Armstrong Roberts ensured the people photographed in "Group in Front of Tri-Motor Airplane" all signed model releases; this allowed others like it to be commercially viable.
In an effort to save the cost of hiring photographers for commission-based photo shoots and advertisers began to consider stock photos as a less risky alternative. One of the first major stock photography libraries was founded in 1920 by H. Armstrong Roberts; the Bettman Archive in New York is an example of an early traditional stock agency, with the company delivering photos upon 24-hour request to magazines such as Look and Life. Founded in 1936 by Otto Bettmann, a German curator who emigrated to the United States in 1935, the Bettman Archive began with Bettmann's personal collection of 15,000 images which he brought with him in suitcases when he escaped from Nazi Germany, he expanded his collection by placing ads in magazines for stills and photos. A different early pioneer with the stock industry was photographer Tony Stone, whose portfolio of mountain scenes proved popular with chocolate advertisers. Stone's stock library reached 20,000 images, each selected for its likelihood to sell multiple copies.
Known as a stock resource for newspapers and magazines, the Hulton Archive started as the photographic archive of Picture Post. As the archive expanded through World War II, it became clear that its vast collection of photographs and negatives were becoming an important historical documentary resource. In 1945, Sir Edward Hulton set up the Hulton Press Library as a semi-independent operation and commissioned Charles Gibbs-Smith of the Victoria and Albert Museum to catalogue the entire archive using a system of keywords and classifications; the Gibbs-Smith system claims to be the world’s first indexing system for pictures, it was adopted by the British Museum collections. By the 1980s, stock photography had become a specialty in its own right, with the stock industry advancing quickly; as photo libraries transitioned from physical archives to servers in the mid-1990s, "stock libraries" were called "stock agencies." The archives began to rely on keywords for sorting and retrieving photographs.
In 1991 Photodisc in Seattle, Washington began selling CD ROMs with packs of images. Unlike their competitors, Photodisc licensed. In contrast to the Rights Managed system, royalty free allowed the purchaser of a CD ROM to use the images as many times as they liked without paying further fees. There was a great amount of consolidation among stock photo agencies between 1990 and the mid-2000s, with Corbis notably acquiring the massive Bettmann Archive in 1995. After Photodisc went online in 1995, in September 1997, PhotoDisc agreed to combine with London-based Getty Communications to form the Seattle-based Getty Images. In 1996, the Hulton Picture Collection was bought by Getty Images for £8.6 million. Alamy is a owned stock photography agency launched in 1999. Alamy maintains an online archive of over one hundred million still images and hundreds of thousands of videos contributed by agencies and independent photographers or collected from news archives and national collections, its suppliers include both professional and amateur photographers, stock agencies, news archives and national collections.
Its clients are from the photography and advertising industries and the general public. The early microstock company iStockphoto was founded in May 2000. A free stock imagery website, it transitioned into its current micropayment model in 2001. IStockphoto co-founders Bruce Livingstone and Brianna Wettlaufer went on to start Stocksy United in 2013.

Photography is the art and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science and business, as well as its more direct uses for art and video production, recreational purposes and mass communication. A lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, electronically processed and stored in a digital image file for subsequent display or processing; the result with photographic emulsion is an invisible latent image, chemically "developed" into a visible image, either negative or positive depending on the purpose of the photographic material and the method of processing. A negative image on film is traditionally used to photographically create a positive image on a paper base, known as a print, either by using an enlarger or by contact printing.
The word "photography" was created from the Greek roots φωτός, genitive of φῶς, "light" and γραφή "representation by means of lines" or "drawing", together meaning "drawing with light". Several people may have coined the same new term from these roots independently. Hercules Florence, a French painter and inventor living in Campinas, used the French form of the word, photographie, in private notes which a Brazilian historian believes were written in 1834; this claim is reported but has never been independently confirmed as beyond reasonable doubt. The German newspaper Vossische Zeitung of 25 February 1839 contained an article entitled Photographie, discussing several priority claims – Henry Fox Talbot's – regarding Daguerre's claim of invention; the article is the earliest known occurrence of the word in public print. It was signed "J. M.", believed to have been Berlin astronomer Johann von Maedler. The inventors Nicéphore Niépce, Henry Fox Talbot and Louis Daguerre seem not to have known or used the word "photography", but referred to their processes as "Heliography", "Photogenic Drawing"/"Talbotype"/"Calotype" and "Daguerreotype".
Photography is the result of combining several technical discoveries, relating to seeing an image and capturing the image. The discovery of the camera obscura that provides an image of a scene dates back to ancient China. Greek mathematicians Aristotle and Euclid independently described a pinhole camera in the 5th and 4th centuries BCE. In the 6th century CE, Byzantine mathematician Anthemius of Tralles used a type of camera obscura in his experiments; the Arab physicist Ibn al-Haytham invented a camera obscura and pinhole camera. Leonardo da Vinci mentions natural camera obscura that are formed by dark caves on the edge of a sunlit valley. A hole in the cave wall will act as a pinhole camera and project a laterally reversed, upside down image on a piece of paper. Renaissance painters used the camera obscura which, in fact, gives the optical rendering in color that dominates Western Art, it is a box with a hole in it which allows light to go through and create an image onto the piece of paper.
The birth of photography was concerned with inventing means to capture and keep the image produced by the camera obscura. Albertus Magnus discovered silver nitrate, Georg Fabricius discovered silver chloride, the techniques described in Ibn al-Haytham's Book of Optics are capable of producing primitive photographs using medieval materials. Daniele Barbaro described a diaphragm in 1566. Wilhelm Homberg described how light darkened some chemicals in 1694; the fiction book Giphantie, published in 1760, by French author Tiphaigne de la Roche, described what can be interpreted as photography. Around the year 1800, British inventor Thomas Wedgwood made the first known attempt to capture the image in a camera obscura by means of a light-sensitive substance, he used paper or white leather treated with silver nitrate. Although he succeeded in capturing the shadows of objects placed on the surface in direct sunlight, made shadow copies of paintings on glass, it was reported in 1802 that "the images formed by means of a camera obscura have been found too faint to produce, in any moderate time, an effect upon the nitrate of silver."
The shadow images darkened all over. The first permanent photoetching was an image produced in 1822 by the French inventor Nicéphore Niépce, but it was destroyed in a attempt to make prints from it. Niépce was successful again in 1825. In 1826 or 1827, he made the View from the Window at Le Gras, the earliest surviving photograph from nature; because Niépce's camera photographs required an long exposure, he sought to improve his bitumen process or replace it with one, more practical. In partnership with Louis Daguerre, he worked out post-exposure processing methods that produced visually superior results and replaced the bitumen with a more light-sensitive resin, but hours of exposure in the camera were still required. With an eye to eventual commercial exploitation, the partners opted for total secrecy. Niépce died in 1833 and Daguerre redirected the experiments toward the light-sensitive silver halides, which Niépce had abandoned many years earlier because of his inability to make the images he captured with them light-fast and permanent.
Digital rights management
Digital rights management tools or technological protection measures are a set of access control technologies for restricting the use of proprietary hardware and copyrighted works. DRM technologies try to control the use and distribution of copyrighted works, as well as systems within devices that enforce these policies; the use of digital rights management is not universally accepted. Proponents of DRM argue that it is necessary to prevent intellectual property from being copied just as physical locks are needed to prevent personal property from being stolen, that it can help the copyright holder maintain artistic control, that it can ensure continued revenue streams; those opposed to DRM contend there is no evidence that DRM helps prevent copyright infringement, arguing instead that it serves only to inconvenience legitimate customers, that DRM helps big business stifle innovation and competition. Furthermore, works can become permanently inaccessible if the DRM scheme changes or if the service is discontinued.
DRM can restrict users from exercising their legal rights under the copyright law, such as backing up copies of CDs or DVDs, lending materials out through a library, accessing works in the public domain, or using copyrighted materials for research and education under the fair use doctrine. The Electronic Frontier Foundation and the Free Software Foundation consider the use of DRM systems to be an anti-competitive practice. Worldwide, many laws have been created which criminalize the circumvention of DRM, communication about such circumvention, the creation and distribution of tools used for such circumvention; such laws are part of the United States' Digital Millennium Copyright Act, the European Union's Copyright Directive. The rise of digital media and analog-to-digital conversion technologies has vastly increased the concerns of copyright-owning individuals and organizations within the music and movie industries. While analog media lost quality with each copy generation, in some cases during normal use, digital media files may be duplicated an unlimited number of times with no degradation in the quality.
The rise of personal computers as household appliances has made it convenient for consumers to convert media in a physical, analog or broadcast form into a universal, digital form for portability or viewing later. This, combined with the Internet and popular file-sharing tools, has made unauthorized distribution of copies of copyrighted digital media much easier. In 1983, a early implementation of Digital Rights Management was the Software Service System devised by the Japanese engineer Ryuichi Moriya. and subsequently refined under the name superdistribution. The SSS was based on encryption, with specialized hardware that controlled decryption and enabled payments to be sent to the copyright holder; the underlying principle of the SSS and subsequently of superdistribution was that the distribution of encrypted digital products should be unrestricted and that users of those products would not just be permitted to redistribute them but would be encouraged to do so. Common DRM techniques include restrictive licensing agreements: The access to digital materials and public domain is restricted to consumers as a condition of entering a website or when downloading software.
Encryption, scrambling of expressive material and embedding of a tag, designed to control access and reproduction of information, including backup copies for personal use. DRM technologies enable content publishers to enforce their own access policies on content, such as restrictions on copying or viewing; these technologies have been criticized for restricting individuals from copying or using the content such as by fair use. DRM is in common use by the entertainment industry. Many online music stores, such as Apple's iTunes Store, e-book publishers and vendors, such as OverDrive use DRM, as do cable and satellite service operators, to prevent unauthorized use of content or services. However, Apple dropped DRM from all iTunes music files around 2009. Industry has expanded the usage of DRM to more traditional hardware products, such as Keurig's coffeemakers, Philips' light bulbs, mobile device power chargers, John Deere's tractors. For instance, tractor companies try to prevent farmers from making DIY repairs under usage of DRM-laws as DMCA.
Computer games sometimes use DRM technologies to limit the number of systems the game can be installed on by requiring authentication with an online server. Most games with this restriction allow three or five installs, although some allow an installation to be'recovered' when the game is uninstalled; this not only limits users who have more than three or five computers in their homes, but can prove to be a problem if the user has to unexpectedly perform certain tasks like upgrading operating systems or reformatting the computer's hard drive, tasks which, depending on how the DRM is implemented, count a game's subsequent reinstall as a new installation, making the game unusable after a certain period if it is only used on a single computer. In mid-2008, the Windows version of Mass Effect marked the start of a wave of titles making use of SecuROM for DRM and requiring authentication with a server; the use of t
