Talk:35 mm movie film

Differences in Movie and still film
I don't know exactily today what's in kodak eastman catalog but a few years ago colors films were different but the B & W were excatlly the same. This mainly IMHO due to the use of artificial light.(by the way motion picture use mainly negative film like most amateur photographer and not inversible film like in super 8). About the perforation it seems there is a super 35mm variant with different perforations. But in seems perforation in movie film could differ at differnet stages between the negative and the final copy to avoid geometrical distortions.

I found this about the subject but I did not read in extenso. http://www.kodak.de/US/en/motion/students/handbook/perforations1.jhtml Ericd 09:54 Sep 7, 2002 (UTC)

Super 35

 * My understanding of Super 35 is that a larger picture area is used, including the soundtrack area; this corresponds roughly with the picture area available in the silent area. For theatre distribution the top and bottom are cropped and the image is optically squished to standard anamorphic widescreen size, while for video & TV the exact picture size can be tailored scene-by-scene -- unlike conventional pan & scan, wide scenes can be preserved by zooming out and including that top and bottom space that was cropped out of the theater release. As far as I know there's nothing special with perforations, but I could be wrong. --Brion 22:38 Sep 7, 2002 (UTC)

I don't know exactly how it's done but super 8, super 16, super 35 are always the same trick : a larger image with the same film width. For super 8 that's done with different perforations for super 16 and super 35 I don't know. Ericd 22:54 Sep 7, 2002 (UTC)

Same trick: smaller perforations. Look at the end of film formats, I've put in a link to a site with over hundred movie formats - it is an truly excellent site.

I've made a 135 film page too, for photography. There is still a few sentences about photography in 35mm film - IMHO they should be moved to 135. I know the film medium is basically the same, but I would say a split with cross links is the best solution. A reader would normally be intested in either the photo or the movie side - and of course should be told about the connection User:Egil

DH perforation
Found a mistake with the radius of the hole corner roundings of the Dubray-Howell perforation. It should be 0.013" or 0,33 mm as with the AC type (CS), not 0.02" or 0,5 mm. --Filmtechniker (talk) 15:24, 21 August 2019 (UTC)
