Why is it that with over 60 years of improvements in cameras, lens sharpness and film grain, resolution and dynamic range that no one has been able to equal what Ansel Adams did back in the 1940s?

• 为何在60年后的今天，当摄影器材不论是在照相机的功能、镜头的锐利度、底片的细致度以及解析度都已经改进到一定的程度，却仍然没有人能够取代或甚至拍出相同于安塞亚当斯(AnselAdams)在1940年代所拍摄的作品？
