It ... depends.
That can be done in either. To a degree of course. What it requires is a deep understanding of 1) what the difference is between seeing at night versus daytime; 2) how media shot at night naturally differs from that shot in daytime as the viewers are familiar with that and 3) how the specific software used can best accomplish the job.
How it can fake the look, essentially ... because a good day for night is not a recreation of "reality" but a display of elegant fakery. Allowing the viewers to suspend disbelief with ease.
If the scene/s are fairly simple, PrPro and the Lumetri panel can do well.
If you need to mask a ton of skies and lights and replace parts of the scene, AfterEffects has better extreme tracking and masking abilities.
So ... how extensive is the job?
Thank you for the advice and theory. Currently I'm working on a late afternoon street shot with very little sky and shadow via iphone 6 cam so it should be simple enough with premiere. Looking forward to trying out after effects with further footage. So, in terms of masking objects... AE is the way to go?
You can do a lot of stuff in Pr, but it takes work.
As for AE it takes less effort.
And AE is designed for 'fancy' stuff.
