Assuming one wants the visual technique of Christopher Nolan that we've come to know and love to continue post-Pfister, the article argues that he needs to find a DP who'll share "similar aesthetics and technical passions." So, maybe instead of who you'd like to see be his next cinematographer, who do you think would do the best job of preserving the director's aesthetics?
Don't over estimate Pfister's importance. He is a great DP. One of the best right at the moment. But, Pfister himself told that the most important part of a movie is not how you light a movie but what's the story of this movie.
Nolan can be a DP. Following already have the aesthetics of all his movies so don't worry too much. Nolan, it's first a story experience then everything else (casting, music, editing, light, sound, stunt & sfx)
