I'm going to try to make sense -- bear with me, English is not my first language.
I was watching Mad Men, and I was really puzzled. What are the elements that make it look different from the movie shot in the sixties?
I read somewhere the DP tried to shoot like they used to shoot then, but yet, it's a total different feel.
Is it maybe the fact that colors mutate with time in the film itself? Like bread that becomes stale after few days?
Even in exterior shots, where there is not much lighting manipulation... you can see if something was shot 30 years ago or recently... why?
