CBC's Andrew Chang in Rio: what the cameras don't show

Presumably many of you havebeen watching the Olympic coverage on CBC: it's wall-to-wall, on every platform, every device, at almost every hour.

But what aren't you seeing?

The main Barra Olympic Park was built in such a way as to create exquisite sightlines from many different angles. Great pains are taken to be able to set up at specificvantage points to capture it.

But it's also not hardwith a little bit of walking around to see the Olympic underbelly: construction materials, portables, wires and cables.

It's the side to Rio you don't often see on TV.

But to be fair, even CBC's carefully crafted shoots areless than lavish.

Often when you see beautifully lit interviews with wonderful backgrounds, you might imagine they were done on an expansive set with huge crews and lots of equipment.

But more often than not, especially abroad, it's a pretty bare-bones setup.

Shelter for rain, lights, a riser, a tripod, and a camera those are the basic ingredients.

The host city generally handles the rest.
