quote: John Pytlak
Much as I would like to encourage 65mm production for feature films again
John, what are the likely oposition arguments for not using 65mm from the studios? What could you do in Kodak to encourage 65mm production? Could seminars be organised for directors of photography? Could examples of restored prints be shown to exhibitors? Could a deal be struck for purchase of 35mm and 70mm negative which satisfies both Kodak and the studios?

quote: John Pytlak
(e.g., anamorphic origination, avoid underexposing the film, use 4K post-production, etc.).
John: Is digital production avoidable when there are no digital effects to insert? Don’t you think that digital post-production interferes with the “film look”? I have nothing against people wanting to get other looks, but how about cinematographers who want to keep the film look, is this possible nowadays? And, what would be the minimum scan resolution to do justice to 65mm negative?

quote: Scott Jentsch
The key is to differentiate the blowups from the "purebreds" easily. It shouldn't be hard for consumers to understand or diminish the overall positive message that you want to impress people with, but there should be a way to pick out the 35>70 blowups from the 65>70 presentations.

This is a very interesting point. Actually the numbers itself could be used. Nowadays everybody likes to use “versions” one could be the big screen experience version 35.70 and the other the big screen experience version 65.70 . [Big Grin]

quote: Bobby Henderson
The dawn of the multiplex era happened during this time as well. Numerous shoe-box sized screens built in cookie-cutter fashion replaced a great deal of palacial single screeners during that period. That factor alone probably did more to kill 65mm production than anything else.
Palatial single screeners are the most valuable and most expensive piece of cinema hardware, and the saddest thing of all is that we cannot recover them. When Lawrence of Arabia was re-released in 70mm in Barcelona in the 80s it was in one of those magnificent cinemas. The print was shown in V.O. with subtitles (unheard of for a big cinema in Barcelona) and the shows were fully booked. I remember taking many friends of mine who were marvelled at the beauty of the image, the big slightly curved screen, the curtains, … The lights started to dim with the curtains closed, then only some lights beneath the curtains were left on and the intro music started, after the intro music finished the curtains opened!!!! That was showmanship, what a presentation, those were the times when screens would be framed for 35mm presentation as to use the biggest area for the 70mm presentations. If they had provided more 65mm films those cinemas would have survived.

quote: Larry Myers
So if you have 4 viewers on a 8 ft wide screen or 800 viewers on a 80 foot wide screen, it will matter not to the viewer. It might be a bid deal for the theater owner as far as ticket sales but the viewer could care less.
I personally could not care less about this theory, which obviously does not apply to my perception of screens. Shoeboxes multiplexes [puke] are crap, killjoys, and have done a lot of damage to cinema exhibition. It was a short-term solution. They have got no future at all and they might as well demolish them. Now when the video projectors are installed they have got even less sense. Why pay £8 for one of those small, badly decorated and full of popcorn mini screeners to get a video projection when you can get a video projection at home without the popcorn?

Again it's all in the numbers and these are text book numbers. It all has to do with visually geometrical relationships between film resolution, screen size, view distance. Again text book stuff.

So let me get this correct. You want to call a meeting together of experts in the motion picture industry and tell them 70mm is way cool stuff and why don't you people give us some more?

That's dumb guy stuff right out of the projection booth. They are all going to come back and say hey, just take the film out of the can and load the projector. We would really just like to see the damn movie.

I do admit though, there are a few technical reasons why an image may look better blown up very large and viewed from a greater distance. This is in contrast to a much smaller image viewed at a closer distance. The reason is the Modulation Transfer Function or MTF designed into movie film. Anyone know what this is?

The DC sales force promises extra revenue to offset the gigantic cost; showing football finals, for instance. In our State we have massive clubs in every town; they make their money like casinos, with alcohol and gaming. They show all the big sporting events in their auditoriums and it will be petty cash to them to go 2K digital and oh, pity the local cinema closed coz it can’t get film any more. No matter, you can watch it at the club with a beer.
The best DC demo I have seen was a Sony on a 60 foot screen, but the source material was film – large format, including IMAX.

It matters not to each viewer if the screen is 80 ft wide viewed at 90 ft or or 8 ft wide viewed at 9ft. The screen will look exactly the same size.
That's not quite so. Brightness is a major factor. If I watch a 35mm print on a 70' screen it is going to look noticeably more dim than the same print shown on a smaller screen and from a proportionately similar viewing distance.

I don't know the details about the deal AccessIT and Christie made with Carmike Cinemas. But it doesn't sound like Carmike is having to foot the entire bill for installing 2400+ 3-chip 2K DLP video projection systems. If the film distributors pay the entire cost of projector installations, their investment can pay for itself in about 5 years. Consider how many 35mm prints any given 1st run theater projector will play per year -at a cost of $1000 to $3000 per print. I just wish they were going with 4K on this.

Blow ups started in 1963 with "The Cardinal" - if it wasn´t for blow-ups, the 70mm format would never have been so popular among audience and film makers. The process is nearly as old as Todd-AO and the number of titles premiered as "blow ups" outnumbers 65mm films many times.

Larry, you have been so rude in the past and you continue being that way that sometimes I cannot help but use your sarcastic tone.

You have been proven wrong in the past. I do not know the intricacies of many technical aspects of film but it seems that you apply the principles wrong, like with the frame space of a 65mm negative which stores three times more information and hence the increase in image quality. And let’s not mention the comparison of the Ben-Hur scans!!!

Also you do not mention anything about film presentation. Regardless of the small screen size, the majority of shoeboxes cinemas are to film exhibition what fast food chains are to food, execrable! Granted, some of the old cinema palaces had bad seats as well but the good ones were amazing. Going to the pictures was a thrill, an event. Whoever is over 35 years old has experienced this thrill. These big palaces gave more thrill than any IMAX presentation. Also they used to have magnificent displays outside the cinema advertising the film. It was a completely different thing.

Your rudeness and disregard for film projectionist has got no justification.

I am not a film projectionist, but I would certainly trust much more film projectionist than you. The majority of them know very much about film projection, as it is obvious from their statements on this website. Not only that, this is their job, and the good ones are going to know about it, aren’t they?

I still do not know what is your point and doubt if anyone will. It has been proven that 65/70 is much, much, much, much better that 2k digital projection and that 35mm projection. So what is your point now? What is your objective?

I am just a member of the audience who used to enjoy going to the pictures and I am giving my input. I am not a technician and I may be wrong. Not only that, obviously, not everybody will feel the cinema experience as I do, this is just normal. Have you ever gone to the pictures with your friends and find out that you do not agree where to sit, front, middle, rear? We are all different individuals and I do not know if your book mentions that. But I have been going to the pictures for 39 years and I know many people who go to the pictures as well.

For some bizarre reason I was able to spot pan and scan on telly (one of the biggest abominations of this world) at a tender age. Not only that, I used to be able to spot if a film shown on TV had been filmed in Metrocolor, Colour by DeLuxe, three-strip Technicolor or the extremely ugly Eastman colour that was used in Spain during the 60s and 70s.

The “experts” who deal with the business of cinema exhibition must have done something wrong, because this is an extremely failing business. It has been going down for many years, and it does not look this is going to stop with the arrival of high definition television.

Films last so little nowadays that sometimes it is not possible to see them in your vicinity. Also the majority of local multiplexes show the same films, which are usually very bad films.

Somehow I understand the digital phenomena. Businesses are going so bad for film exhibition in theatres that they might as well try and save as much as possible.

People certainly go to the pubs to see sport events, they will not go to the pictures for it. DC promoters have also mentioned that they will broadcast music concerts, I doubt anyone will go to that. I like music very much and if I want to listen to a concert I go there, especially if it is a classical music concert, since you do not get the digital intermediate in between, acoustic straight to your ear! If it is a Jazz concert, either I go there and enjoy the real thing or buy a DVD and watch it at home as many times as I want. If people do not go to theatres to see pictures they will even go less to see telly, the proposal of alternative material is just preposterous.

I have also seen some nice blow-ups, the nicest one being Pathfinder, a very beautiful film with amazing photography. The print I saw was done at the Technicolor labs and it was very nice. However, I doubt blow-ups will really solve the problem of cinema exhibition, since they will only be used for the big screens and the quality of the negative remains the same. Basically I do not think there is change enough for distributors to consider it. Anyway, I have exposed my points and I won’t repeat myself. This is the reason why I am insisting on something revolutionary, for cinemas to subsist they need a unique product, something that cannot be experienced at home. This is why I insist on the Cinerama experience. Cinemas have not had an exclusive product for many years, this is the reason they are doing so bad. They have nothing to sell.

Well it works like this.

A 2 inch by 2 inch image is TWICE the size of an 1 inch by 1 inch image. Each side is MAGNIFIED 2 times. That means twice the resolution and 4 times the area for light. One image is 1 sq inch and the other is 4 sq inches.

If the 2 inch by 2 inch image is 40 lines per millimeter resolution with a 80mm lens, then the the 1 inch by 1 inch image needs to be 80 line per millmeter with a 40mm lens for both images to have the exact same detail.

So the jump from 35mm true scope to 70mm is 1.5 times and not 3 times. If 35mm to 70 mm jump was three times, the 70mm image would need to be 12 perf high and we all know that's not correct. The jump to Cinemascope 55 from 35mm true scope is only 2 times with it's 8 perf high image.

And as far as screen size. Size is size. The sun is way brighter then the moon but yet, both appear the same size from our point of view on earth.


Again text book stuff.

Anyone can massage and data-mine numbers to try to spin whatever argument they're trying to support.

Regardless of what any numbers say, 5 perf 65mm motion picture quality has a much higher potential of image quality than 4-perf 35mm. Simple as that. Many of the participants in this thread have seen the gigantic difference. Any numbers thrown out there will not refute that.

I don't even know what Larry's point is any more. Seems as though he just likes to throw numbers around.

Size does matter in film presentation. That includes the size of each frame of projected image, the size (scale) of the screen, the "size" of the sound system, room acoustics, etc. Field of vision is not everything. I can sit 4 feet from my widescreen TV and it will fill my field of vision. Does that mean the experience is the same as seeing a movie on a 60' screen?

IMHO, experiencing "The Sound of Music" or "Titanic" in a good 70mm theatre far surpasses the "home theatre" experience. Over the last forty years, my most memorable and enjoyable movie-going experiences have been with 70mm presentations.

OK, here goes nothing:

Dimensions are in inches unless otherwise stated.

The 'scope projector aperture is 0.838x0.700 (0.5866 sq inches)
The flat projector aperture is 0.825x0.466 (0.3675 sq inches)
The 70mm projector aperture is 1.912x0.87 (1.66344 sq inches)
If 70mm was 1:2.4 (possible with digital sound) it would be 2.088x0.87 (1.81656 sq inches)
70mm in 1:1.85 is 1.6095x.87 (1.400265 sq inches)

Therefore, GIVEN THE SAME FILM TECHNOLOGY AND SAME FRAME COMPOSITION:

For the flat, 1:1.85 ratio, 70mm has 3.81 times the image area of 35mm which means it has 3.81 times the resolution and will let 3.81 times as much light through.

For 'scope 1:2.4 ratio (with digital sound 70mm can show the full width), 70mm has 3.1 times the image area of 35mm true 'scope which means it has 3.1 times the resolution and will let 3.1 times as much light through.

If you want to go with the standard 70mm 1:2.2 ratio, 70mm has 2.84 times the image are of 35mm true 'scope which means it has 2.84 times the resolution and will let 2.84 times as much light through.

In conclusion, given equivalent film technology and frame composition, it is abundantly clear that for any aspect ratio 70mm film will have significantly more image detail on the release print and have significantly greater light efficiency than 35mm.

John, you are correct (of course!). I can recall so many memorable 70mm presentations, practically all of them blowups too. For many years, the Edwards Big Newport ran 70mm almost exclusively, one engagement after another, and they were often great filmgoing experiences. "Amadeus", Star Wars trilogy, Star Treks 2 and 3, and on and on. They shrewdly installed 70mm in the 2nd and 3rd houses too, which were much smaller, just so they could have that 70mm logo as a draw, and of course, so they could move prints around if necessary, based on what was selling the most tickets, and not have to drop the 70mm presentation.

I'm very pessimistic about the prospects for a 70mm revival (no matter how the prints are originated). But damn, it would be a helluva good thing for movie theaters if they could bring back that magic. Cuz 70mm brings magic to the screen more often than not.

I already loved movies when I was a kid. But 70mm is the thing that made me very interested in the technical side. 70mm is the thing that made me take notice of a stellar presenation quality and the big differences between watching movies at home on TV versus seeing them in really good theaters.

..and I also agree with John with all of the 70mm presentations that I've seen - 2001:a Space Odyssey - Ryan's Daughter - TRON - Logan's Run - The three Indiana Jones releases (blown up 35mm relases) - Brainstorm - Alien - the first three Star Wars.

Then what's really interesting is that I ran all of these in the 35mm format and the difference is obvious that 70mm presentation outshines any 35mm presesntation.

I'd like to see what kind of numbers Larry can produce in comparing 15/70 against the 5/70 (and,even toss 8/70 in there)..

Since many movies are edited digitally, and printed from a far off negative from the original, how good could a film these days look on 70mm? I think they're outputted onto film at 2k for 35mm, it seems that they'd need to output it at 4k for 70mm?
