Dunkirk 是 65mm 胶片拍摄的
国内也没有 70mm IMAX 放映
再怎么说,大屏幕都是第一位的,所以选 IMAX 是没跑的,而且这一部没有 Dolby Atmos,更何况其他屏幕都是切割过的
> If there isn ’ t an IMAX theater showing it in 70mm film near you, the next best option is IMAX Laser, which might be 1.43:1 or, at worst, 1.90:1, and it will almost certainly have better black levels. If that ’ s not an option, next best is IMAX xenon digital at 1.90:1. Given the choice between regular 70mm film and digital cinema, I would choose digital cinema — especially Dolby Cinema — at 2.20:1. For me, the last choice is 35mm film, which has the most cropping at 2.35:1 and the poor black levels of film.
