Compositing

Introduction

Compositing is a set of numerical methods of mixing multiple image sources into a plan that will be unique built-in mounting. For an animated film, this is the final manufacturing step that consists of assembling all layers of scenery, characters and realizes the effects of camera to animate some travel, and special effects. In film shooting, the purpose is to achieve special effects and fake videos. This is one of the last links in the chain of the image in a film. Sources can be images scanned from film, drawing, video; digital images (drawings, 3D, special effects). This paper discusses the compositing in detail.

Compositing

Compositing may be, within the constraints of the sources, made ??frame by frame or automated. One of the most perfect examples of compositing is Who Framed Roger Rabbit in which actors are filmed and mixed cartoon. Compositing is a term used in video and film technology and is in post-production of a film as visual effects application. In compositing to merge two or more separately recorded or created elements into one image. In computer graphics compositing is meant by the joining of several superimposed layers of a volume behind. Compositing is the process of merging multiple image elements into a coherent whole (Wright, 2001, pp. 56).

Film

Visual effects describe all effects that cannot be achieved by conventional photographic means. These can be done through compositing. Examples of compositing are the combining of images (Footages) by blue screen / green screen and multiple exposures, as in the movie Metropolis. Before the advent of digital imaging, the effect of compositing was achieved by using multiple projectors (Brinkmann, 1999, pp. 97). The various images were projected onto a screen, where a camera was added, for example, a character appeared in a film by the inclusion of these copied into an existing character in film. However, due to these methods the mechanical and image quality suffered which is why it was usually only applied in the short term.

Refinements of this technique have been on a large scale for the first time in the movie Blade Runner applied in the year 1982. In this movie, many settings of miniature models, matte background, rain and live action shots were combined. With the film Indiana Jones and the Last Crusade (1989), this technique was first created in the computer. For this, the footage was digitized by an image processing software together and then transferred back to film. From the mid-1990s, compositing was also used to digitally insert generated characters in live-action shots, e.g. Jurassic Park (1993), Godzilla (1997). The most well-known company in this area is Industrial Light ...
