PhotographA photograph (also known as a photo, or more generically referred to as an image or picture) is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor. The process and practice of creating such images is called photography. Photographs are now created using a smartphone or camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would perceive.
Image sensorAn image sensor or imager is a sensor used for imaging. It converts light into electrical signals, small bursts of current in proportion to the light intensity. The pattern of electrical signals conveys the information in the image.
CameraA camera is an instrument used to capture and store images and videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research.
Photographic filmPhotographic film is a strip or sheet of transparent film base coated on one side with a gelatinemulsion containing microscopically small light-sensitive silver halide crystals, for the purpose of taking photographs. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film. Film is typically segmented in frames, which give rise to separate photographs.
ImageAn image or picture is a visual representation. An image can be two-dimensional, such as a drawing, painting, or photograph, or three-dimensional, such as a carving or sculpture. Images may be displayed through other media, including a projection on a surface, activation of electronic signals, or digital displays; they can also be reproduced through mechanical means, such as photography, printmaking, or photocopying.
PhotographerA photographer is a person who makes photographs, most commonly using a camera. They may do so as part of photojournalism, for the sake of creating personal mementos, as part of a business model, as artistic expression or for various other reasons. Photography has become extremely widespread and common in the 21st century. The term photographer is typically applied more narrowly to one who practices photography as a serious or semi-serious pursuit.
PhotolithographyPhotolithography (also known as optical lithography) is a process that involves using light to transfer a pattern onto a photoresist layer deposited on a sample, typically a silicon wafer. It is used in the manufacturing of integrated circuits. The process begins with a photosensitive material, called a photoresist, being applied to the substrate. A photomask that contains the desired pattern is then placed over the photoresist.
Mass communicationMass communication is the process of communicating and exchanging information through mass media to large population segments. It utilizes various forms of media as technology has made the dissemination of information more efficient. Primary examples of platforms utilized and examined include journalism and advertising.
LightLight, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometers (nm), corresponding to frequencies of 750–420 terahertz.
FilmVisual art consisting of moving imagesA Trip to the Moon (1902) is considered to be a turning point in the development of narrative and science fiction films.A film, movie, or motion picture is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, emotions, or atmosphere through the use of moving images that are generally, since the 1930s, synchronized with sound and sometimes feature other sensory stimuli.
Visual artsThe visual arts are art forms such as painting, drawing, printmaking, sculpture, ceramics, photography, video, image, filmmaking, design, crafts, and architecture. Many artistic disciplines such as performing arts, conceptual art, and textile arts, also involve aspects of the visual arts, as well as arts of other types. Within the visual arts, the applied arts, such as industrial design, graphic design, fashion design, interior design, and decorative art are also included.Video productionVideo production is the process of producing video content. It is the equivalent of filmmaking, but with video recorded either as analog signals on videotape, digitally in video tape or as computer files stored on optical discs, hard drives, SSDs, magnetic tape or memory cards instead of film stock. There are three main stages of video production, pre-production, production and post-production.
