这个我知道,蝙蝠侠2部都是,貌似现在就这4部电影。所以sony这个还是比不过imax胶片。但是能把平均水平提 ...
你的理解有一点问题! IMAX拍摄,主要是为了获得 70mm大尺孔的超大视角的全景画面。 因为拍摄后,依然要扫描成数字版本去制作特效。而扫描后其分辨率只能维持在 6K x 3K的水平(因为目前胶片转数字的扫描设备,最高能进行 6K x 3K的原底扫描)。
所以实际上,制作完特效后,无论是以数字版的 IMAX放映,还是重新扫回胶片,以胶片版的 IMAX放映,若以“数码的概念”套分辨率的话,它的理论分辨率水平,都不可能超过 6K x 3K!
数字拍摄的好处是原始处理,拍完了原始的数字底片后,根本无须扫描,直接把 RAW毛片拿去后期制作就可以了(不像胶片转数字后,损耗巨大)。 所以 F65RS本身拍摄的信息量是多少,其后期制作的毛片就能保证拥有多少信息量。
而且 2013年 4月的 NAB, SONY已经打算对 F65RS的 CMOS传感器进行升级,升级后,其将支持完整的:8K x 4K(8,192 x 4,320)的3,500万像素分辨率的输出!(那就真的是恐怖的“超级数字版的 IMAX” 了)。

Sony Details F65 Roadmap Heading into 2013
6 10 0 18
By Bryant Frazer / Oct 30, 2012
Along with the splashy announcement of the new F5 and F55 CineAlta 4K cameras came word of forthcoming firmware upgrades for Sony's flagship F65, including new signal formats to take advantage of its unique 8K x 2K sensor.
First up, and due before the end of the year, is a v2.2 update to remote-control capabilities that will improve the camera's functionality in live situations, such as sports coverage.
Next spring, we should see version 3.0 demonstrated at NAB. The F65 currently generates a 4K x 2K RGB signal from its sensor, but this upgrade will enable 8K x 4K, 6K x 3K, and 8K x 2K.
At a press briefing earlier this month, Sony Electronics Director of Marketing and Product Management Taturo Kurachi nodded toward new anamorphic glass from Zeiss as an example of an application for an 8K x 2K image. "With the glass technology Zeiss puts together, they will appreciate that someone is creating something like 8K x 2K RGB from an 8K-sensor camera," he said. "This anamorphic experience is not stretching or diluting information. It's really taking full advantage of the 8K sensor in the F65."
Version 3.0 firmware will be a paid update. Sony has not yet said how much it will cost.
