70 mm (horizontal) (IMAX DMR blow-up) (Kodak)

and the aspect ratios of the DMR'ed films are maintained, they are letterboxed to fit the IMAX ratio,

and I doubt they do any DNR on the 35mm masters, since the grain are huge on the IMAX screen,

I have seen DMR'ed movies one more than one instance, and I hate the quality,

the size of the image is great, but the quality is bad, the sharpness of the image is lost, and the details are lost in grain.

not the best experience, I often choose a 35mm or a 4k showing of a film in oppostion to a DMR'ed show.

for me, the quality of DMR'ed film in IMAX are mixed bag, some look great sometimes not. Spiderwick Chronicles looked hazy and quite frankly terrible. The latest Star Trek looked amazing and of course sounded incredible. Inception on the big IMAX screen was impressive, but for a film where certain scenes were shot in 70mm - I couldn't tell, the image again looked hazy and didn't have that 'pop' sheen look that IMAX-Digital conveyed.

Technically there shouldn't be any, or let me restate very little, grain on an IMAX (film) print. Films that are transferred for IMAX-Digital, DLP and Sony LCoS '4K' use the intermediate negative or digital capture where very little grain is actually captured on film, if you see a film festival or premier engagement those prints are also truer to what was originally shot, mass produced 35mm prints actually look far worse than what was shot by the Director of Photography, unless he/she wants the movie to purposely have a grainy appearence (i.e, the Saw films sans 'Saw 3D')

The plus side of IMAX - is that the majority of the films soundtracks are remixed to Sonics DDP sound

Some of the recent ones look great, like Grand Canyon Adventure, The Alps, and Wild Ocean.

And Baraka is not IMAX. It's regular vertical 70mm where each frame is 5 perforations high. IMAX cameras feed the 65mm film horizontally and each frame is 15 perforations wide.

what's the point/importance of perforations, I've never understood why that's such a major factor when frame/film stock is mentioned.

speaking of new IMAX blurays - I saw this on the IMAX screen and the review of the bluray is a 'must buy':

The same film director and crew are soon to release Samsara which is being filmed in Super Panavision 70 and after its initial theatrical release will reach Blu-Ray with the same results. So 70mm is not exactly dead and buried. It keeps on coming back. Look at the recent restoration of The Sound of Music (1965) also produced in Todd-AO and scanned from the original 65mm negatives at 8K resolution. Really, who needs IMAX? 70mm photography is definitely more expensive than 35mm Super 35 or 35mm anamorphic Panavision. A feature film in IMAX is not only cost prohibitive and impossible as the IMAX camera when in use is so loud and noisy it would become a distraction for actors and film crew and a nuisance as live sound recording would have to be ruled out and replaced with dubbed dialogue. 70mm (actually 65mm negatives) could be selectively used in productions which lend themselves to epic storytelling and extra clarity would benefit the film as a whole. Bypassing the theatrical distribution of 70mm movies at exhibition for the lack of venues available could be compensated in possible addition benefits of Hi Def cable and Blu-ray releases. 70mm movies being restored for Blu-Ray are being well received now that the crucial investments in technical support software have now been developed. Those same results could be taken advantage of by today's moviemakers. Excuse me as I ramble on here, but, it could happen... and should happen.

there's speculation that Samsara wont be released in 70mm due to the cost and lack of number of theatres that can still playback 70mm films. The trend of shooting certain scenes for films in 70mm seems odd since a full length film would make a lot more sense

The International
The New World
The Prestige
Quantum of Solace
Shutter Island
Inception

I think that 'Chitty Chitty Bang Bang (IMO) looks better than 'Sound of Music' where the colors seem waaay to saturated for my taste, CCBB looks exceedingly sharp and more natural
