Geoffrey Coalter/Nikon McNally took over 30 wedding portraits on the first day alone.Over the course of two days last week, camera giant Nikon set up a portrait studio in the back of a truck outside City Hall in New York City. 
Its mission: surprise a bunch of newlyweds with free wedding pictures shot by photographer Joe McNally.
In addition to the photos, couples were also treated to hair and makeup services (if they so chose) in a nearby tent.
I caught up with 16 of the happy duos to find out more about their love stories, and why they chose a City Hall wedding.
