Editing Guidelines Please remember these guidelines when editing a film article: If a non-film article already exists with the name of the film that you are trying to create an article for, disambiguate and use (film) in the title: Film Title (film) For more information see: Wikipedia:Naming conventions (films) When writing an article about a particular film, the general format should be a concise lead section, followed by a plot summary of no more than 900 words, production details, a cast list, a reception section, and references. Create an Infobox that tells all pertinent information about the film.
Additional Information: This article has been checked against the following criteria for B-Class status: Referencing and citation: not checked Coverage and accuracy: not checked Structure: not checked Grammar: not checked Supporting materials: not checked To fill out this checklist, please add the following to the template call: <!-- 1. It is suitably referenced, and all major points are appropriately cited. --> |B-Class-1=yes/no <!-- 2. It reasonably covers the topic, and does not contain major omissions or inaccuracies. --> |B-Class-2=yes/no <!-- 3. It has a defined structure, including a lead section and one or more sections of content. --> |B-Class-3=yes/no <!-- 4. It is free from major grammatical errors. --> |B-Class-4=yes/no <!-- 5. It contains appropriate supporting materials, such as an infobox, images, or diagrams. --> |B-Class-5=yes/no Related task forces (general): Filmmaking task force

This is a very technical explanation. I'd like to help put it into plain English, but don't want to get anything wrong. Howabout, for example: "It relies on replacing parts of one image with another. This is achieved by making transparent any part of the image which is a specified colour (e.g. green, blue, or black). This allows a second image to 'show through', creating a composite." --Rayray 11:34, 23 November 2005 (UTC)

[edit] Merging

In my opinion, there ought to be (at least) two articles. One (this page) should be about compositing in relation to filmmaking, covering practical techniques and products. Another, currently alpha compositing, should focus on the theory (Porter-Duff, etc.), mathematics, and its relation to software and computer graphics. The audience of the first page would be the layman/filmmaker, and that of the second page a mathematician/computer scientist. Perhaps we should work to move the math to alpha compositing. --IanOsgood 04:02, 20 July 2006 (UTC)

[edit] γ

γ is introduced without a description equivalent to the description for α, being "the opacity value of the foreground pixel" Hackwrench 07:22, 31 July 2006 (UTC)
