I was reading the AC magazine's January issue, the article about La La Land and I've seen this picture
Then I recalled that the shot in the film was a night so I found it. (Don't ask me how )
I'm sure this is the shot, I've checked the beginning of the scene as well, for the location.
So my question is, how can you achieve such an exposure with lights in the background, cars and on the trees, do you think there are any digital stuff going on?
