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. Article upgrading needed: You can help! WP:IA   Stub to Start-Class Upgrading Instructions for Films Note that instructions for articles on other types of film topics within the scope of WikiProject Films are currently under development. To contribute in upgrading this stub article to Start class, the following requirements must be met: Significant intro (list the title, alternate titles, year released, director, actors starring in the film, summary of headings, etc.) Film infobox ({{infobox film}}) Picture: Consult WikiProject Free Images for freely released images from a film shoot, opening, or other relevant free image. Non-free and unlicensed images are to be avoided if at all possible, but if used should include a detailed fair use rationale. (An image is not required for start class if unavailable.) Plot summary Include cast and crew information. At least two other developed sections of information (production, reception (including box office figures), awards and honors, themes, differences from novel or TV show, soundtrack, sequels, DVD release, etc.) Categories (by year, country, language, and genre(s))  Helpful links: WP:BETTER, WP:LEAD, WP:REF, WP:WAF Once this article has fulfilled these requirements, the film can be reassessed to Start class and this template will be removed automatically.

[edit] Comments

Note to editors: The 1989 Superbowl halftime show was broadcast in 3D using this technique. (I remember watching it.) According to http://www.davidandmaddie.com/3d.htm , Moonlighting was to be the first TV show that used this, but the writer's strike of 1988 killed their plans. Also according to the same site, the 1989 Superbowl (Actually, a halftime ad for Coke, although I remember the whole halftime show being 3D) was the first time ever this technique was used on TV. Also, this link http://groups.google.com/group/rec.arts.tv/tree/browse_frm/month/1989-01?_done=%2Fgroup%2Frec.arts.tv%2Fbrowse_frm%2Fmonth%2F1989-01%3F& shows a discussion of the show from January 1989, shortly after the superbowl.—The preceding unsigned comment was added by 70.64.68.223 (talk • contribs) 04:21, 3 June 2006 (UTC).

I definately remember watching the famous rose bowl parade in 3-d with this technique. sorry, I dont remember the year. -SF

[edit] stationary objects

I agree that non-moving objects cannot be percieved 3D but I use this effect by making the things rotate. This is a viable possibility and I think it should be noted in the article. —The preceding unsigned comment was added by Honnza (talk • contribs) 16:43, 24 January 2007 (UTC).

[edit] stationary objects

I would point out that if an object is rotating, it is no longer stationary. The object might not change position relative to a fixed reference (e.g., the edge of a monitor or other objects in the immediate area) but the object has motion. It is this point-for-point change in position of the object's image on the retina that produces the Pulfrich stereo-phenomenon.

Another interesting example of the Pulfrich Stereo-phenomenon can be observed with dynamic random noise (DRN), like 'snow' seen on a TV tuned to a blank channel. If you place a dark lens over one eye, say the left, what you will observe is a clockwise-swirling maelstrom. Placing the dark lens over the other eye will reverse its direction.

[edit] Carl Pulfrich

There is an article (yet a stub) about Carl Pulfrich, anybody include a link to it? --129.13.186.1 12:57, 27 April 2007 (UTC)

[edit] One more example

It was used in Canada for Discovery Channel's Shark Week maybe around 5 years ago (I don't remember exactly). The glasses (with one normal lens and one dark one) were included with one of our national newspapers on a certain day (either the Toronto Star, Globe and Mail or National Post). Only the last hour-long shark film of the week was in "3D", and only certain parts of it (there was a sign to put on 3D glasses during the "3D" parts). It looked completely normal on the tv screen without the glasses, but with them there was a 3D effect.

It was about a species of ancient giant shark, if I remember correctly, and many of the 3D parts were CG recreations of the giant shark. I must say that it was a pretty horrible documentary overall; the 3D segments kept repeating themselves and it wasn't very informative or interesting except for the 3D.

Anyway, if anyone can find any information about what this was exactly, that would be one thing to add. Esn (talk) 07:21, 26 February 2008 (UTC)

Oops, I found it. Never mind. Esn (talk) 07:26, 26 February 2008 (UTC)
