Australian Prime Minister Julia Gillard traveled to Beijing this week, for a two-day visit aimed at broadening relations between the two countries.

But capturing those images was more of a challenge than you might think. CNN Beijing producer Jo Kent and photographer Brad Olson take us behind the scenes, to see what goes into getting such an important shot.
