Talk:70 mm film

Changes

I've just done a quick clean up job for this article, I'm going to continue working on it in the coming days. My main problems concern the second portion of the article and how to organize those contents. --Allseeingi 16:54, 22 January 2006 (UTC)

• Just be careful about your pruning. I fear that your current changes have already deleted reference as to the technical superiorities the format has over 35mm as well as the cultural status it held. It's not POV if it's objective, remember. Girolamo Savonarola 23:42, 22 January 2006 (UTC)
  • I've added more to the history section. I'm unsure about how to expand information about the cultural status of the stock. Do you think a new section should be added? --Allseeingi 21:21, 23 January 2006 (UTC)
    • Well, there are many sites devoted to the 70mm format and what it used to mean to see a film like that. I dunno, I mean, if you're not feeling it yourself, don't force it. Girolamo Savonarola 22:56, 23 January 2006 (UTC)
      • I think the section on 65mm/70mm films should be moved to its own article. That would unclutter this page and make it easier to navigate. --Allseeingi 20:45, 24 January 2006 (UTC)

Update: I've added those films to their own page. List_of_70mm_Films--Allseeingi 20:49, 24 January 2006 (UTC)

• I've created sections for the various uses of 70mm film and I've a lot of information from the history section to their appropriate sections. With these changes and a few more, I think this article can soon lose the clean up tag. --Allseeingi 20:20, 28 January 2006 (UTC)

Very good article. I just miss numbers of the costs.

Something I've always wondered, and which this article does not answer - I know 70mm film uses a wider angle, but does that automatically mean a wider or bigger screen? I saw Kenneth Branagh's "Hamlet" in what was supposed to have been 70mm according to the newspaper ad, but it was projected on your ordinary size multiplex wide screen. (?) AlbertSM 02:06, 17 May 2007 (UTC)

I don't understand your usage of wider angle. Wider gauge, certainly. Image projection is always ultimately limited by the physical size of the screen. Most professional theaters change the aspect ratio of the screen by moving the screen's side curtains. Since 70mm is a 2.20:1 ratio, this means that a 35mm anamorphic film (2.39:1) will actually use slightly more of the screen. However, the larger size of the film frame for the 70mm print means that the image should have higher quality, since it requires less magnification and contains more "information" on the print. It should also be noted that virtually all 70mm films created blown-down 35mm prints in order to allow theaters which didn't have 70mm projectors still show the film (and thus make more money). In the past, these prints often were issued weeks or months after the initial 70mm screenings. Girolamo Savonarola 02:29, 17 May 2007 (UTC)

It's just that I've always assumed that because the 70mm film had a picture twice as large as 35mm, then the screen also had to be twice as large as a screen on which 35 mm films were shown. AlbertSM 15:53, 17 May 2007 (UTC)

Nope. The screen may be as large or small as the venue has space for. --brion 16:02, 17 May 2007 (UTC)

Illustration

It would be useful with an illustration of the film strip with perforations, image, sound track, etc. --HelgeStenstrom 13:14, 19 September 2007 (UTC)

I agree. It'd be nice to have a comparison between 70 mm and 35 mm, too, considering the article claims that 70 mm is better. --DearPrudence (talk) 06:34, 1 July 2008 (UTC)

I did a lot of the 35 mm illustrations. I'll dig out my old files and have a go. Megapixie (talk) 12:20, 1 July 2008 (UTC)

Better image?

The 70mm print shown at the top of this article looks to be in pretty bad shape - something with better colour would be a much nicer illustration. David (talk) 11:08, 12 October 2012 (UTC)

Are 70mm blowups actually sharper?

Making it bigger doesn't make it clearer. Once you've exposed and developed the film you can't resolve more detail than is already there. Ranolden (talk) 01:31, 10 March 2024 (UTC)
