Follow Focus
A follow focus is a focus control mechanism used in filmmaking with film cameras and in television production with professional video cameras. It helps the camera operator be more efficient and precise. It is usually operated by a focus puller (often called the 1st assistant camera, or 1st AC), but some camera operators prefer to pull their own focus (the act of changing focus is called "pulling" or racking focus). Overview Manual focusing is usually a requisite for professional filmmaking, because autofocus systems may focus on undesired objects, or fail to adjust quickly enough to sudden changes. The job of the focus puller then is to adjust the focus onto different subjects as well as maintain focus during movement of the camera relative to the subject. The mechanism works through a set of gears on the follow focus that are attached to teeth on the focus ring of the lens. These gears feed to a wheel that, when turned by a focus puller, spins the teeth and thus the ring on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arri 35II With Anamorphic Zoom
Arri Group () (stylized as "ARRI") is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. It is cited by Hermann Simon as an example of a " hidden champion". The Arri Alexa camera system was used to shoot several films that won the Academy Award for Best Cinematography, including '' Hugo'' (2011), ''Life of Pi'' (2012), ''Gravity'' (2013), '' Birdman'' (2014), '' The Revenant'' (2015) and ''1917'' (2019). History Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym ''Arri'' was derived from the initial two letters of the founders' surnames, ''Ar''nold and ''Ri''chter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter i ...

Autofocus
An autofocus (AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers.

Whip Zoom
A whip zoom (also referred to as a snap zoom or crash zoom) is a type of camera shot in which the camera zooms in or out quickly, allowing the viewer to focus on the subject. Another use of the whip zoom is to enable the shot to be edited as a cut from a long shot to a close up, or vice versa. This technique is used by several directors such as Quentin Tarantino, Martin Scorsese, Kevin Smith and Rainer Werner Fassbinder. Examples can be seen in 1970s kung fu film and in the movies '' Kill Bill: Volume 2'', '' Goodfellas'', ''Tusk'', '' Kundo: Age of the Rampant, Man of Steel'' and ''Eight Hours Don't Make a Day ''Eight Hours Don't Make a Day'' () (also translated as ''(Eight Hours Are Not a Day)'' is a West German television miniseries written and directed by Rainer Werner Fassbinder. Commissioned by Westdeutscher Rundfunk, it was broadcast in five e ...''. Horror genre examples can be found in '' The Shining'' and '' The Exorcist III''. References {{filmmaking-stub Ci ...

Follow Shot
Follow shot is a specific camera angle in which the subject being filmed is seemingly pursued by the camera, for example by a Steadicam. The follow shot can be achieved through tracking devices, panning, the use of a crane, and zoom lenses resulting in different qualitative images but, nevertheless, recording a subject (performer) in motion. Usage Follow shots are typically used in film to establish audience alignment with the perspective of the character being followed and to follow them. The audience is made aware of the character's presence and is able to observe them in action, while also being forced to identify with the character. It is considered neither first-person perspective nor third-person perspective. Examples *''Elephant'': Each character is followed continuously during their narrative time. *'' 2:37'': Each character is followed several times, in a style similar to that of the previously-mentioned ''Elephant''. *'' The Shining'': The steadicam Steadicam i ...

Racking Focus
A focus puller or first assistant camera (1st AC) is a member of a film crew's camera department whose primary responsibility is to maintain the camera lens's optical focus on whatever subject or action is being filmed. "Pulling focus" refers to the act of changing the camera lens's focus distance to a moving subject's distance from the focal plane, or the changing distance between a stationary object and a moving camera. For example, if an actor moves from to away from the focal plane, the focus puller changes the lens's distance setting in precise relation to the actor's changing position. The focus puller may also shift focus from one subject to another as the shot requires, a process called "rack focusing". Focus pulling There is often very little room for error, depending on the parameters of a given shot. The focus puller's role is extremely important to a film production. In most circumstances, a "soft" image is considered unusable, as such an error can't be corrected i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosumer
A prosumer is an individual who both consumes and produces. The term is a portmanteau of the words '' producer'' and ''consumer''. Research has identified six types of prosumers: DIY prosumers, self-service prosumers, customizing prosumers, collaborative prosumers, monetised prosumers, and economic prosumers. The terms ''prosumer'' and ''prosumption'' were coined in 1980 by Alvin Toffler, an American futurist, and were widely used by many technology writers of the time. Technological breakthroughs and a rise in user participation blurs the line between production and consumption activities, with the consumer becoming a prosumer. Definitions and contexts Prosumers have been defined as "individuals who consume and produce value, either for self-consumption or consumption by others, and can receive implicit or explicit incentives from organizations involved in the exchange." The term has since come to refer to a person using commons-based peer production. In the digital and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lens (optics)
A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic and are ground, polished, or molded to the required shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called "lenses", such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices such as telescopes, binoculars, and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word ''lens'' comes from , the Latin name of the lentil (a seed of a lentil pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gears
A gear or gearwheel is a rotating machine element, machine part typically used to transmit rotation, rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machining, machined on the part, or separate pegs inserted into it. In the latter case, the gear is usually called a cogwheel. A cog may be one of those pegsDefinition of "cog" in the ''Oxford Learner's Dictionary'' online. Accessed on 2024-07-29.Definition of "cog" in the ''Merriam-Webster Dictionary'' online.

Abel Hidalgo
Abel ( ''Hébel'', in pausa ''Hā́ḇel''; ''Hábel''; , ''Hābēl'') is a biblical figure in the Book of Genesis within the Abrahamic religions. Born as the second son of Adam and Eve, the first two humans created by God, he was a shepherd who offered his firstborn flock to God as a religious offering. God accepted Abel's offering but not the offering of his older brother Cain, leading Cain to stone Abel to death out of jealousy. This act marked the first death in biblical history, making Abel the first murder victim. Life and death Interpretations Jewish and Christian interpretations According to the narrative in Genesis, Abel is Eve's second son. His name in Hebrew is composed of the same three consonants as a root meaning "the air that remains after you exhale" also synonymous in Hebrew to "nothing", as stated in Ecclesiastes. Julius Wellhausen has proposed that the name is independent of the root. Eberhard Schrader had previously put forward the Akkadian (Old Assyrian ...
