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.

[edit] Improvements

This article can be improved in many ways:

• the article title is wrong, it should be Exposure latitude. Stops is the unit how you measure exposure latitude. It's like filing the article about "lenght" under "meter" - it's just wrong.
• equasion - typo. One of many many typos.
• "then we talk about the blacks being more like dark grays and the white have yellowish or blueish hue to them (depending if you are shooting outside or not) " - mixing up of colour temperature and latitude - bad.
• "The colours are more blended into one another" - huh?
• "Each stop is equal to 5.5 dB which is 550,000,000 times brighter than the lowest light level" - what? this makes no sense at all.
• "Most TV's today such as various rear-projection and LCDs, have a 2000:1 contrast ratio about same as film" - bad bad grammar.
• "Contrast ratio is the on/off difference. 1 is off and the high number is on" - this is a travesty.
• "Digital video is only 1.45dB which is way lower than film" ??
• "Video is pretty limited because it only has 145 million variations of different brightness level" - yep. of course. absolutely true numbers, no doubt at all about them...
• Overall, the article seems to just be launch pad for the HDRI article.

Anybody with lots of time to fix it? Cheers! Peter S. 21:44, 30 September 2006 (UTC)

Absolutely agree with Peter.

I would change the article myself, if I had the knowledge. I have a good enough understanding of the subject to work with film, but to give a good explanation of this subject is difficult.

1. It has to restrain itself, and find out if the article is about F/T-Stops, or Dynamic range/Exposure latitude

2. It has to comply with the scientific standards regarding light

3. It has to comply with common film industry terms, that filmmakers understand and work with

4. It's still a pedia, and it has to be readable by layman.

5. This discussion should inspire knowledgeable users to write information in the article.

Judging from Peter S's post and arrogance, I bet he's a working cinematographer. We need people like that to write in the article.

I've removed all the crap. Anyone who wants to add information relative to stops, feel free to do so. ~MDD4696 04:03, 6 December 2006 (UTC)

[edit] Red Camera section reads like ad, plus what are DPs?

Someone with knowledge please clean this up. DP links to a disambiguation page that doesn't help at all since I don't know what it means here. The red camera section reads just like a plug for the product. "Only" 17,500 USD ?!?! Kinda need some context if you are going to say ONLY 17,500! Maybe that is a great bargain, but don't see how it fits here in an encyclopedia article.

Peter S. says it all clearly.

I've deleted this section. First of all, there is no camera yet to speak of or evaluate, so it's all just speculation and uncritical acceptance of promotional info. Second, an encyclopedic article on dynamic range and stops generally should be discussing imaging technologies, not specific cameras or sensors. I wouldn't expect discussion of Red here anymore than I would of a Panaflex, CineAlta, or Kodak's new 5201 stock - discussing film, video, CCDs, CMOSs, etc is what the article should be germane to. Specific products should be largely irrelevant. Girolamo Savonarola 20:14, 25 October 2006 (UTC)
