Prior to the start of the games in Rio we got a glimpse of the gear that Getty photographers are using to cover the Olympics. This week, we've seen a couple more of the tools the organization is using – a pair of robotic underwater camera housings. 

Veteran Getty photographer Al Bello talks about using the robotic camera housing with CNN Money, and says that they give an obvious advantage over the static underwater systems that they've used in the past. The robotic system allows him to pan, tilt and zoom a Canon EOS-1D X II enclosed safely in the housing as athletes pass by overhead, eliminating the guesswork that the static system required. 

You can see more of Bello's work above and below the water in Rio by following him on Twitter and Instagram.
