) Compositing software is used to combine images, and makes extensive use of alpha compositing techniques.

α ( alpha ) has a meaning similar to that in alpha compositing techniques.

Ray Harryhausen extended the art of stop-motion animation with his special techniques of compositing to create spectacular fantasy adventures such as Jason and the Argonauts ( whose climax, a sword battle with seven animated skeletons, is considered a landmark in special effects ).

Two key innovations in the development of the modern music video were the development of relatively inexpensive and easy-to-use video recording and editing equipment, and the development of visual effects created with techniques such as image compositing.

These techniques are generally derived from match moving techniques used in special effects and compositing work.

* It was one of the first comics ( web or print ) to make extensive use of image editing software for " special effects ", by utilizing filters and compositing techniques in Adobe Photoshop and Fractal Painter, and filter suites like Kai's Power Tools.

This can be achieved by over partitioning the object space and assigning multiple pieces to each processing unit in a random fashion, however this increases the number of alpha compositing stages required to create the final image.

A potential solution to the linguistic and cultural bottleneck that held back movable type in Korea for two hundred years appeared in the early 15th century — a generation before Gutenberg would begin working on his own movable-type invention in Europe — when King Sejong the Great devised a simplified alphabet of 24 characters ( hangul ) for use by the common people, which could have made the typecasting and compositing process more feasible.

* Beryl, a compositing window manager forked from Compiz and later merged back

Degradation of film images during compositing was minimized by other innovations: the Dykstraflex used VistaVision cameras that photographed widescreen images horizontally along stock, using far more of the film per frame, and thinner-emulsion filmstocks were used in the compositing process.

Digital compositing allows far more control and creative freedom than optical compositing, and does not degrade the image like analogue ( optical ) processes.

The next generation of CrossFire, as employed by the X1800 Master cards, used two sets of compositing chips and a custom double density dual-link DVI Y-dongle to double the bandwidth between cards, raising the maximum resolution and refresh rate to far higher levels.

Limited use of 65 mm film was revived in the late 1970s for some of the visual effects sequences in films like Close Encounters of the Third Kind, mainly because the larger negative did a better job than 35 mm negative of minimizing visible film grain during optical compositing.

Since the 1990s, a handful of films ( such as Spider-Man 2 ) have used it for this purpose, but the usage of digital intermediate for compositing has largely negated these issues.

In the late 1980s, digital compositing began to supplant optical effects.

; Clipping, masking and compositing

Sprite systems were more efficient for moving graphics, typically requiring 1 / 3 the memory cycles as only image data needed to be fetched, compositing happening on-chip ;

Motion control camera rigs are also used in still photography with or without compositing ; for example in long exposures of moving vehicles.

For the sake of compositing, the background elements of the scene must remain identical between takes, requiring anything movable to be locked down ; the blank reference take can aid in resolving any discrepancies between the other shots.

Thomas J. Harris, in Children ’ s Live-Action Musical Films: A Critical Survey and Filmography, heavily criticizes the story as well as the compositing of the animated Elliott ; he also found the " Mary Poppinsish ending " to be " thoroughly unmotivated ", because Pete's life before meeting Elliott is never fleshed out.

He and Thomas Porter, another Lucasfilm employee, developed a new approach to compositing images ; their 1984 paper, " Compositing Digital Images ",

Microsoft Windows has provided an integrated stacking window manager since Windows 2. 0 ; Windows Vista introduced the compositing dwm. exe as an optional hardware-accelerated alternative.

Currently, SheerVideo contains specific codecs for real-time lossless encoding and decoding of RGB data ( for digitized film and CGI ) as well as Y ' CbCr data ( for video ); with or without an alpha ( A ) channel for compositing ; at a precision of 10 or 8 bits per channel ; fully sampled ( 4: 4: 4 ) or 2: 1 chroma-subsampled ( 4: 2: 2 ); and progressive-scan ( p ) or interlaced ( i ):

However, " The Boy Who Knew Too Much " was one of the few episodes in which technical issues still remained ; for example, Bart and Lisa's image was fuzzy toward the beginning, and the episode featured for the last time " some of the hand drawn dimensions that would be eliminated once the show switched over to digital compositing and desktop cartoon creation ".

The procedure of submitting motions to some conferences includes one or more rounds of compulsory compositing ; in other cases, the compositing may be informal.

A partial solution to this is some programs ' ability to view the composite-order of elements ( such as images, effects, or other attributes ) with a visual diagram called a flowchart to nest compositions, or " comps ," directly into other compositions, thereby adding complexity to the render-order by first compositing layers in the beginning composition, then combining that resultant image with the layered images from the proceeding composition, and so on.

This is in contrast to the node based interface used by some other compositing applications.

While this technique may be possible to accomplish within some stacking window managers, it is technically compositing, with the foreground window and the screen raster being treated the same way two windows would be in a compositing window manager.

Whereas 3ds Max is a comprehensive modeling, animation, and rendering package with some secondary post-production and compositing features, Gmax is much more limited due to its singular intended use — game content creation.

" 3DV " incorporated some of its own innovations like 3D lip-synching and compositing a CG character into a live-action scene but, other than a promotional edit which was shown at SIGGRAPH, this too went nowhere.

Motion is a motion graphics and compositing application similar in some ways to After Effects and Nuke.

With properly installed drivers, and GPU hardware such as supported Intel, ATI, and nVidia chip sets, some window managers, called compositing window managers allow windows to be separately processed and then rendered ( or composited ).

This had some buggy corner cases, but more or less worked, until compositing entered into the desktop.

A *( B *( C * D )) where A, B, C, D are partially transparent image layers and "*" denotes a compositing operator ( with the left layer on top of the right layer ).

For compositing operators that are commutative, such as additive blending, it is safe to re-order the blending operations.

There are two radically different digital compositing workflows: node-based compositing and layer-based compositing.

In contrast to compositing window managers ( see below ), the lack of separate offscreen buffers can mean increased efficiency, but effects such as translucency are not possible.

Modern GPUs are designed primarily for 3d and add the ability to modify bitmaps in mathematically advanced ways, allowing arbitrary image transformations, texture decompression and filtering, shading for illumination models, alpha blend compositing operations, and depth-buffer comparison / update.

Other effects are often used along with motion control, such as chroma key to aid the compositing.

Compiz and KWin are compositing window managers for systems using the X Window System.

All window managers that allow the overlapping of windows but are not compositing window managers are considered stacking window managers, although it is possible that not all use exactly the same methodologies.

Alpha compositing and therefore transparency effects, such as fade effects in menus, are not supported by the GDI in Windows 9x.

In addition, the rules for compositing many overlapping objects allow choices, such as whether a group of objects are blended before being blended with the background, or whether each object in turn is blended into the background.

While not exclusive in their usage of computer technology, they are given praise for their advances in digital compositing, digital effects, digital image / story boarding, and digital color grading.

Its main uses are the origination of 2D and 2. 5D animation, visual effects compositing and finishing ( image adjustment, color correction etc .).

Although other compositing packages — especially ones that employ tree or node workflows, such as Nuke are better suited to manage large volumes of objects within a composite, After Effects is able to somewhat counter the clutter by selectively hiding layers ( using the Shy switch ) or by grouping them into pre-compositions.

Since many window managers are modular, people can use others, such as Compiz ( a 3D compositing window manager ), which replaces the window manager.

All window managers that have overlapping windows and are not compositing window managers are stacking window managers, although it is possible that not all use the same methods.

In e-commerce, image servers are qualified by their abilities to scale to hundreds of thousands of images, to multiple CPUs or load-balanced server machines, and to the quantity and quality of their image processing functionalities, such as resizing, compositing, zoom and 3D viewers, and the addition of dynamic data to the images in the form of overlaid text or graphics.

In physical compositing the separate parts of the image are placed together in the photographic frame and recorded in a single exposure.

The most common physical compositing elements are partial models and glass paintings.
