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.

I've cleaned the article up a bit, but it needs a better statement about the range of digital sensors, supported, of course, by a verifiable source. JeffConrad 07:31, 29 April 2007 (UTC)

[edit] So what does it *do*?

For the first time, while playing with my new DSLR last night, I realised that "exposure compensation" is simply the camera adjusting other factors to give greater exposure. For example, if in "aperture priority" mode, you increase the "exposure compensation" it will actually probably increase the ISO rating and/or shutter speed. If my understanding is correct, then the explanation in this article could be improved a lot, by making it more concrete: "Increasing the exposure compensation tells the camera to use a wider aperture, slower shutter speed, or higher ISO rating, or some combination of the above." But since I'm a camera newbie, I'm not game to write it myself :) Stevage 02:37, 29 June 2007 (UTC)

I've added a brief description of how the exposure compensation feature is usually implemented; I've gone no further because this article is about exposure compensation and not about exposure and how that is affected by camera settings. In theory, a camera also could vary ISO speed, but negative compensation could be a problem if the camera were already set to a low speed such as ISO 100. Bear in mind that the concept of what exposure compensation is doing is more important than how it is effected. JeffConrad 07:48, 29 June 2007 (UTC)
