Recently I was asked by Airbag to complete a matte-painting to be used in a series of TVC's for the NBN Network - Australia's broadband network. The requirement was for a generic or 'every' Australian city, featuring a skyline comprising of buildings from all the major cities. It was to look familiar yet non-specific and be set during the 'Magic Hour'. It was a fun project made slightly more difficult by the fact that the matte preceded filming and I didn't have a plate to work with.
I also manually created a depth mask to provide greater control over the layers to the compositor.
Two of the three TVC's featuring the matte have so far been released. Blink and you'll miss it!
