In-camera Effect
An in-camera effect is any special effect in a video or movie that is created solely by using techniques in and on the camera and/or its parts. The in-camera effect is defined by the fact that the effect exists on the original camera negative or video recording before it is sent to a lab or modified. So effects that modify the original negative at the lab, such as skip bleach or Flashing (cinematography), flashing, are not included. Some examples of in-camera effects include: * Matte painting * Schüfftan process * Forced perspective * Dolly zoom * Lens flares * Lighting effects * Photographic filter, Filtration such as using a fog filter to simulate fog, or a grad filter to simulate sunset. * shutter (photography), Shutter effects. * Time-lapse, slow motion, fast motion, and speed ramping. * Bipacks * Slit-scan photography, Slit-scan * Infrared photography * Reverse motion * Front projection * Rear projection * Phonotrope a live animation technique that uses the Frame rate, frame-r ...

Special Effect
Special effects (often abbreviated as SFX, F/X or simply FX) are illusions or visual tricks used in the theatre, film, television, video game, amusement park and simulator industries to simulate the imagined events in a story or virtual world. Special effects are traditionally divided into the categories of mechanical effects and optical effects. With the emergence of digital film-making a distinction between special effects and visual effects has grown, with the latter referring to digital post-production and optical effects, while "special effects" refers to mechanical effects. Mechanical effects (also called practical or physical effects) are usually accomplished during the live-action shooting. This includes the use of mechanized props, scenery, scale models, animatronics, pyrotechnics and atmospheric effects: creating physical wind, rain, fog, snow, clouds, making a car appear to drive by itself and blowing up a building, etc. Mechanical effects are also often inco ...

Speed Ramping
Slow motion (commonly abbreviated as slo-mo or slow-mo) is an effect in film-making whereby time appears to be slowed down. It was invented by the Austrian priest August Musger in the early 20th century. This can be accomplished through the use of high-speed cameras and then playing the footage produced by such cameras at a normal rate like 30 fps, or in post production through the use of software. Typically this style is achieved when each film frame is captured at a rate much faster than it will be played back. When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second). Slow motion can also be achieved by playing normally recorded footage at a slower speed. This technique is more often applied to video subjected to instant replay than to film. A third technique uses computer software post-processing to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optical Printing
An optical printer is a device consisting of one or more film projectors mechanically linked to a movie camera. It allows filmmakers to re-photograph one or more strips of film. The optical printer is used for making special effects for motion pictures, or for copying and restoring film material. Common optical effects include fade outs and fade ins, dissolves, slow motion, fast motion, and matte work. More complicated work can involve dozens of elements, all combined into a single scene. History The first commercially available, although not mass produced, optical printer appeared in 1927 and was called the Depue & Vance Daylight Optical Printer. It was mainly used to reduce standard prints to 16mm and allowed for operation without a darkroom except from loading the positive film magazine. In 1918, the cinematographer Carl Gregory came upon a printer made by G. J. Badgley of New York, designed to produce copies of a standard film using domestic size film stock. Realizing ...

Cinematic Techniques
This article contains a list of cinematic techniques that are divided into categories and briefly described. Basic definitions of terms ;180-degree rule :A continuity editorial technique in which sequential shots of two or more actors within a scene are all shot with the camera on one side of the two actors so that a coherent spatial relationship and eyeline match are maintained. ;Airborne shot :A shot taken from an aerial device, generally while moving. This technique has gained popularity in recent years due to the popularity and growing availability of drones. ;Arc :A dolly shot where the camera moves in an arc along a circular or elliptical radius in relation to the subject ("arc left" or "arc right") ;Backlighting (lighting design) :The main source of light is behind the subject, silhouetting it, and directed toward the camera. ;Bridging shot :A shot used to cover a jump in time or place or other discontinuity. Examples are a clock face showing advancing time, falling cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camera Effects
Camera Effects was a film opticals ( post-production and visual effects) studio based in Soho, London from 1964 till its closure in 1987. It had a world wide reputation for producing film special effects and titles for television commercial and feature film projects. The company produced title sequences for major features such as The Three Musketeers, The Rocky Horror Picture Show, Tommy, the Superman films and Supergirl. The company was started by Roy Pace using an animation rostrum camera in a basement at 2 Bourchier Street in 1964. It moved premises to 6 Dean Street, then to 147 Wardour Street before finally settling at 8–11 Bateman Street as the biggest optical house in Soho with six camera rooms, an optical printer and two film studios. Film opticals were created using Oxberry aerial image cameras, with "many animation techniques used in the process." The combination of an animation stand with a 35mm projector enabled the fast turnaround of film opticals and was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Star Trek
''Star Trek'' is an American science fiction media franchise created by Gene Roddenberry, which began with the eponymous 1960s television series and quickly became a worldwide pop-culture phenomenon. The franchise has expanded into various films, television series, video games, novels, and comic books. With an estimated $10.6 billion in revenue, it is one of the most recognizable and highest-grossing media franchises of all time. The franchise began with ''Star Trek: The Original Series'', which debuted in the US on September 8, 1966 and aired for three seasons on NBC. It was first broadcast on September 6, 1966 on Canada's CTV network. It followed the voyages of the crew of the starship USS ''Enterprise'', a space exploration vessel built by the United Federation of Planets in the 23rd century, on a mission "to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before". In creating ''Star Trek'', Roddenberry w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frame Rate
Frame rate (expressed in or FPS) is the frequency (rate) at which consecutive images (frames) are captured or displayed. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate may also be called the , and be expressed in hertz. Frame rate in electronic camera specifications may refer to the maximal possible rate, where, in practice, other settings (such as exposure time) may reduce the frequency to a lower number. Human vision The temporal sensitivity and resolution of human vision varies depending on the type and characteristics of visual stimulus, and it differs between individuals. The human visual system can process 10 to 12 images per second and perceive them individually, while higher rates are perceived as motion. Modulated light (such as a computer display) is perceived as stable by the majority of participants in studies when the rate is higher than 50 Hz. This perception of modulated light as steady is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonotrope
The Phonotrope is the term coined by animation director Jim Le Fevre to describe the technique of creating animation in a 'live' environment using the confluence of the frame rate of a live action camera and the revolutions of a constantly rotating disc, predominantly (but not exclusively) using a record player. It is a contemporary reworking of the phenakistiscope, one of several pre-film animation devices that produce the illusion of motion by displaying a sequence of pictures showing progressive phases of that motion. The crucial difference between the technique that the Phonotrope uses and the one a phenakistiscope uses is that the Phonotrope is specifically an in-camera technique using the frame-rate of a live-action camera set to a high shutter speed in confluence with a constantly rotating disc to create the illusion of movement. In a phenakistiscope it is the vertical slits in the circumference of the disc that create the stroboscopic interruptions needed for animation ...

Rear Projection
Rear projection (background projection, process photography, etc.) is one of many in-camera effects cinematic techniques in film production for combining foreground performances with pre-filmed backgrounds. It was widely used for many years in driving scenes, or to show other forms of "distant" background motion. Technique Actors stand in front of a screen while a projector positioned behind the screen casts a reversed image of the background. This requires a large space, as the projector needs to be placed some distance from the back of the screen. Frequently the background image may initially appear faint and washed out compared to the foreground. The image that is projected can be still or moving, but is always called the ''plate.'' One might hear the command "Roll plate" to instruct stage crew to begin projecting. These so-called ''process shots'' were widely used to film actors as if they were inside a moving vehicle, who in reality are in a vehicle mock-up on a sound st ...

Front Projection
A front projection effect is an in-camera visual effects process in film production for combining foreground performance with pre-filmed background footage. In contrast to rear projection, which projects footage onto a screen from behind the performers, front projection projects the pre-filmed material over the performers and onto a highly reflective background surface. Description In contrast to rear projection, in front projection the background image is projected onto both the performer and a highly reflective background screen, with the result that the projected image is bounced off the screen and into the lens of a camera. This is achieved by having a screen made of a retroreflective material such as Scotchlite, a product of the 3M company that is also used to make screens for movie theaters. Such material is made from millions of glass beads affixed to the surface of the cloth. These glass beads reflect light back only in the direction from which it came, far more eff ...

Reverse Motion
Reverse motion (also known as reverse motion photography or reverse action) is a special effect in cinematography whereby the action that is filmed is shown backwards (i.e. time-reversed) on screen. It can either be an in-camera effect or an effect produced with the use of an optical printer. There are various reasons why this technique may be adopted, such as for comedic effect (destruction reversal) or for safety reasons (a car stopping just in time may be filmed starting at the stop point). Uses Artistic There are several uses for reverse action. Some are artistic in nature. For example, reverse action can be used for comedic effect. Or it can be used to bring things "back to life" on screen, by filming a process of destruction or decay in reverse. Sometimes it is necessary, for the intended effect to be achieved, for all actions other than the one that it is intended to reverse to be performed, during shooting, backwards—actors have to perform their actions and dialogue backwar ...

Infrared Photography
''Top:'' tree photographed in the near infrared range. ''Bottom:'' same tree in the visible part of the spectrum. In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets infrared (IR) light pass through to the camera, but blocks all or most of the visible light spectrum (the filter thus looks black or deep red). ("Infrared filter" may refer either to this type of filter or to one that blocks infrared but passes other wavelengths.) When these filters are used together with infrared-sensitive film or sensors, "in-camera effects" can be obtained; false-color or black-and-white images with a dreamlike or sometimes lurid appearance kn ...
