Videography in the context of "Electronic media"

Digital imaging or digital image acquisition is the creation of a digital representation of the visual characteristics of an object, such as a physical scene or the interior structure of an object. The term is often assumed to imply or include the processing, compression, storage, printing and display of such images. A key advantage of a digital image, versus an analog image such as a film photograph, is the ability to digitally propagate copies of the original subject indefinitely without any loss of image quality.

Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation, as they pass through or reflect off objects, conveys the information that constitutes the image. In all classes of digital imaging, the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image. For example, the medium of visible light allows digital photography (including digital videography) with various kinds of digital cameras (including digital video cameras). X-rays allow digital X-ray imaging (digital radiography, fluoroscopy, and CT), and gamma rays allow digital gamma ray imaging (digital scintigraphy, SPECT, and PET). Sound allows ultrasonography (such as medical ultrasonography) and sonar, and radio waves allow radar. Digital imaging lends itself well to image analysis by software, as well as to image editing (including image manipulation).

Live action is a form of cinematography or videography that uses photography instead of animation. Some works combine live action with animation to create a live-action animated feature film. Live action is used to define film, video games or similar visual media. Photorealistic animation, particularly modern computer animation, is sometimes erroneously described as "live action", as in the case of some media reports about Disney's remake of the traditionally animated The Lion King from 1994. According to the Cambridge English Dictionary, live action involves "real people or animals, not models, or images that are drawn, or produced by computer".

Content creation is the act of producing (and sharing) information or media content for specific audiences, particularly in digital contexts. A content creator is the person behind such works. According to Dictionary.com, content refers to "something that is to be expressed through some medium, as speech, writing or any of various arts" for self-expression, distribution, marketing and/or publication. Content creation encompasses various activities, including maintaining and updating web sites, blogging, article writing, photography, videography, online commentary, social media accounts, and editing and distribution of digital media. In a survey conducted by the Pew Research Center, the content thus created was defined as "the material people contribute to the online world". In addition to traditional forms of content creation, digital platforms face growing challenges related to privacy, copyright, misinformation, platform moderation policies, and the repercussions of violating community guidelines.

Color temperature is a parameter describing the color of a visible light source by comparing it to the color of light emitted by an idealized opaque, non-reflective body. The temperature of the ideal emitter that matches the color most closely is defined as the color temperature of the original visible light source. The color temperature scale describes only the color of light emitted by a light source, which may actually be at a different (and often much lower) temperature.

Color temperature has applications in lighting, photography, videography, publishing, manufacturing, astrophysics, and other fields. In practice, color temperature is most meaningful for light sources that correspond somewhat closely to the color of some black body, i.e., light in a range going from red to orange to yellow to white to bluish white. Although the concept of correlated color temperature extends the definition to any visible light, the color temperature of a green or a purple light rarely is useful information. Color temperature is conventionally expressed in kelvins, using the symbol K, which are units for absolute temperature.

SZ DJI Technology Co., Ltd. or Shenzhen Da-Jiang Innovations Sciences and Technologies Ltd. (Chinese: 深圳市大疆创新科技有限公司; pinyin: Shēnzhèn Shì Dà Jiāng Chuàngxīn Kējì Yǒuxiàn Gōngsī) or DJI (大疆创新; Dà Jiāng Chuàngxīn), is a Chinese technology company headquartered in Shenzhen, Guangdong. DJI manufactures commercial unmanned aerial vehicles (drones) for aerial photography and videography. It also designs and manufactures camera systems, gimbal stabilizers, propulsion systems, enterprise software, aerial agriculture equipment, and flight control systems.

DJI accounted for over 90% of the world's consumer drone market as of June 2024. Its camera drone technology is widely used in the music, television, and film industries. The company's products have also been used by military and police forces, as well as terrorist groups, with the company taking steps to limit access to the latter.

DeviantArt (formerly styled as deviantART and thus abbreviated as dA) is an American online community that features artwork, videography, photography, and literature, launched on August 7, 2000, by Mathew Stephens, Scott Jarkoff and Angelo Sotira, among others.

DeviantArt is headquartered in the Hollywood area of Los Angeles, California. DeviantArt had about 36 million visitors annually by 2008. In 2010, DeviantArt users were submitting about 1.4 million favorites and about 1.5 million comments daily. In 2011, it was the thirteenth largest social network with about 3.8 million weekly visits. Several years later, in 2017, the site had more than 25 million members and more than 250 million submissions. In 2025, it reached a new milestone with 100 million registered users.

A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical (plumb). It is called a "spirit level" because the liquid inside its vial is commonly alcohol, or "spirit". The name refers to this alcohol-based solution, which, along with an air bubble, indicates whether a surface is level or plumb. Alcohol was historically preferred over water because it has a wider temperature range, won't freeze, and provides less friction for the bubble, ensuring greater accuracy and longevity of the tool. Two basic designs exist: tubular (or linear) and bull's eye (or circular).Different types of spirit levels may be used by carpenters, stonemasons, bricklayers, other building trades workers, surveyors, millwrights and other metalworkers, and in some photographic or videographic work.
