oh and Noticed today that one of Kodak's Bigest movie film customers has been Knighted for his contributions to "Film" and will now be Sir Christopher Nolan. https://www.dailymail.co.uk/tvshowb...estitures-Hollywood-blockbusters-success.html
when a movie is made on 35mm film, the camera cranks through 24 "half frame" size images each second, so the film travels at 90 feet a minute. the Negative comes as 400ft or 1000 ft rolls. a 400ft roll is good for under 4 minutes of shooting
Actually, on a 400 ft reel using 24 fps 4-perf pulldown, you get 4 minutes 26 seconds.
But a lot of movies now, because they intend to use digital editing, will record 24 fps 3-perf pulldown in a wide screen ratio and get 5 minutes 55 seconds on the 400 ft reel.
But I still prefer the traditional 4-perf pulldown in 1.37:1 "Academy" ratio or 1.85:1 "Wide Screen" ratio.

Thanks for sharing that pic. It’s a whole ‘nother world I know nothing about, and it’s cool.

What's interesting, just like selecting portions of digital sensors to get a different format (ie 16:9 vs 4:3 vs 3:2) , only a part of the same film frame is used. You don't get more resolution because the format is wider either with digital or with film. I always assumed that wide screen like Panavision means more film. I suppose there's more film used with IMAX.
Kodak better start churning out film. The Reformed Film Lab folks imported direct from Japan some ordinary Fujicolor 100 ISO print film that they're selling for $25 US.
bfilm showed the Anamorphic format, (their have been a few variations. that actually does use a bit more film area per frame whicl sticking to 4 Perf Pulldown. the reason is that when Sound was added, the entire frame shrunk to keep the same aspect ratio and so the unused area between images was incresed. Anamorphic can allow the frames to have the interframe spacing that existed in the days before Soundtracks as the image is stretched vertically on the film, and then stretched back horizontaly to make for a wider screen. The first Process using the method was CinemaScope. exclusive to 20th Century Fox. CinemaScope used print film with special smaller perforations (called CS Perfs) which becase the process was exclusive to fox were sometimes Dubbed "Fox Holes" this allowed room for a sound track. The Robe in September of 1953 was the first CinemaScope release.I always assumed that wide screen like Panavision means more film. I suppose there's more film used with IMAX.

the one that still folks might relate to is VistaVison (tm) Motion Picture High Fidelity.. https://en.wikipedia.org/wiki/VistaVision
the format transports the film Horizontally like IMAX, with a Pull down of 8 Perfs, the same as our still cameras. While only a few full movies were released in VistaVision, it is relevant in Special effects like the early Star wars Movies.
the next step before IMAX is 5 Perf 65/70 mm (65mm Negative printed on 70mm perfed to match 65mm stock) again to allow for stereo sound.
IMAX uses 65mm/70mm with 15 perf Pulldown, and to get that to work there was a LOT of shredded film until they came up with a working transport.
at the other end of the film format scale, the wikipedia article on 16mm film still shows this picture of three of my dogs who have sadly passed on https://en.wikipedia.org/wiki/16_mm_film#/media/File:16mmBWrevDP.png
Increase availabilityCan you say what you believe to be the reasons why the shutdown gíves you hope that it will result in a price cut on all films?
Exactly what I meant.Investment costs don't necessarily mean higher prices. They can now produce more film and subsequently increase sales while the cost per unit goes down.

the only real stonghold was in special effects, where the bigger negative gave more room to get everything lined up. the Wikipedia article talks about one of the Two VistaVison High speed Cameras ending up at Industrial Light and Magic.and the improving quality of the film stocks making larger film area not particularly necessary, the 35mm vertical pulldown formats were still the choice for most movies.
Thanks for the info. As a kid growing up in the 1950s, I was always impressed when a film was shot in Technicolor, although that had to do with color rather than format. MAybe that's why I like Velvia 50 today.
BUT back in the 1930s, they were often made on Nitrate Stock.
for that mater, I somehow am grated by something produced with a glorified Video Camera and projected in a theater with a fancy Video Projector as a "film" (even if said fancy Projector is designed in Kitchener Ontario https://www.christiedigital.com/about/ )I don't approve of the misuse of the word as a generic reference to film. Celluloid is a very specific and neat material. Even if it was decided to not be the ideal material for a film base, it is still sometimes used for things
Being something of a perfectionist, one of the things that bugs me about the modern motion picture industry, even Eastman Kodak themselves, is their continued use of the term celluloid to refer to film. Celluloid hasn't been used for film since the 1950s, when they changed to acetate "safety" film.
...
I think Nitrate was finally phased out about 1951. Nitrate held on as it was considered to have better physical properties when New, and the tendency was to destroy the prints after the movie had finished playing in Theaters.The change to safety film happened earlier, it was the 30s i think, but during wartime they sometimes again did use celluloid as it apparently is cheaper in production.
I have always thought VistaVision interesting for this reason, as it is a very similar film area to that used by our 35mm still photography cameras. Some movies recorded on VistaVision are White Christmas, To Catch a Thief, High Society, and North by Northwest.
But it was very rarely projected in the original recording format, because very few places had the capability to project the horizontal "pulldown" film. It was usually made to a 35mm release print that used the standard vertical pulldown in the same format as the Academy "Wide Screen" 1.85:1 aspect ratio.

Paramount suggested 2.00:1 as the largest aspect ratio that should be used, but 1.85:1 was the most used, as it made good use of the original film area and also matched a standard format on the release print. The 1.33:1 ratio was only used for television. The recording was always done with spherical lenses, but it was also possible to make an anamorphic "squeeze" print for projection with anamorphic lenses -- but a normal release print was more common.

VistaVision was a fairly short-lived format. Between the higher cost because of using a larger quantity of film and the improving quality of the film stocks making larger film area not particularly necessary, the 35mm vertical pulldown formats were still the choice for most movies.
