After dabbling with acting and music, Greg Downing found his true calling in all things photography related — and the world is a better place for it. His passion for the medium took him from home experiments with plaster casts and turntables to create panoramas of European landmarks to building a new HDRI camera for effects house Rhythm & Hues.

At the same time, Greg has indulged his passion for documenting the wonders of the world with cutting-edge technology. He's used gigapixel photography, photogrammetry, VR, HDRI, dome theaters and the Google Maps API to capture and display Yosemite's El Capitan rock formation, Everest's base camp and historic paintings in Chinese caves. In this podcast, Greg talks about these projects as well as his work with Björk in Iceland on her immersive VR album "Vulnicura" and his collaborations in the world of lightfields with technology pioneer Paul Debevec at Google.
