I'm getting married in the morning

I was on the roof of 'The Mayfair Library' in Central London (for work obviously!) when I spotted some wedding photos being done down below.

As well as being a Library, the location is also a beautiful building and has a registry office (https://www.westminster.gov.uk/mayfair-library-2) and it would appear is popular for chinese/asian weddings...I only say this because most of the photos inside are wedding photos of chinese / asian brides having their photo done at the telephone box outside.
