From what I am finding, the film was shot with 35mm film using Panavision Panaflex Millennium Cameras with Panavision T-Series lenses. For the purpose of the film being shown digitally upon its release, the digital intermediate has been mastered in 4K. This is good as many of the most recent films are mastered in 2K which is the picture quality you get on your High Definition televisions now and in theaters using digital projection...even though some of these films were shot digitally in higher resolutions (4K, 6K or greater) depending on the capture device being used. Many 4K UHD Blu-ray releases are mastered from 2K sources. Interestingly, films that were originally shot in 35mm, 65mm or 70mm have the potential of looking far better than recent films finished in 2K resolution. So, a 4K release of LAWRENCE OF ARABIA mastered from a 70mm print/negative could potentially look far better than a recent film shot digitally and mastered in 2K.
At this point, I want to ask your forgiveness. I've been writing and editing this message for about an hour now...and I hope it is ultimately not too confusing.
Regarding IMAX, originally this process of filming with IMAX cameras using 65mm film, produced films that looked fantastic when presented in theaters designed to showcase the format. Spielberg's WEST SIDE STORY, being mastered in 4K, has the ability to look amazing if it is shown in theaters with 4K technology (which is not readily available in theaters today). If it is shown digitally in 2K, it will look as good as any film you could see in theaters the last time you actually went to a movie theater.
Finally, Spielberg shot the film with an aspect ratio of 2.39:1...so this is a real widescreen movie. If the film was formatted for IMAX presentation, the picture would not be nearly as "wide"...probably something closer to a 1.78:1 aspect ratio. It would completely fill your television screen in the IMAX format, but Spielberg's original film would be presented with black bars at the top and bottom of your television screens now...but you would be seeing EVERYTHING Spielberg intended you to see...nothing would be cropped out.
I hope this made sense. I'm posting now, but additional research on your part should confirm what I'd hoped to convey.
