That is NOT a photoshopped picture. It’s from Getty Images, AUTHENTICATED.

I’m surprised at you - who told you that?
It was just a flash. The lighting of the figures does not match the background. Maybe it was London Fog? LOL. IT just looks photoshopped to me, the buildings have different shadowing than the figures do. It looks like a cut out on a movie set.
