Demetri Portelli is known for his live-action stereo work. He has 25 years of technical camera experience as a camera operator and a technician.

Demetri started 3D shooting as a puller of the IO and convergence with the Resident Evil franchise on Phantom slow motion cameras, then ESPN sports, and the Winter Olympics I.O.C. footage, before his camera test for Robert Richardson ASC and Martin Scorsese’s first digital ARRI project, Hugo. Hugo may also be one of very few films shot 100% natively to win the cinematography Oscar. Demetri went on to capture and supervise 47 Ronin for Universal pictures, then onto one of his favorite creative projects with Jean-Pierre Jeunet shooting The Young and Prodigious T.S. Spivet, employing playful wide lenses and great 3D production design. For this film they won Best 3D Film at Camerimage. Demetri has additionally supervised stereo for the animated film NextGen and has employed 2D-3D post conversion for the Russian fantasy film, He Dragon.

Working with Ang Lee on two ground-breaking HFR native 3D projects, Billy Lynn’s Long Halftime Walk and Gemini Man, has been a realization of a much-improved stereoscopic experience. Ang’s dedication to in-camera 3D quality has allowed the entire team to refine their craftsmanship while exploring possibilities to elevate 3D intimacy and immediacy using HFR/HDR and laser projection for an improved stereo cinema experience.

He has won Best Live-Action Stereography Creative Arts Lumiere Awards twice, both with Hugo (2012) and The Young and Prodigious T.S. Spivet (2014), plus the Advanced Imaging Society’s 2019 "Technology Award" for 3D/120FPS-HFR for his team’s groundbreaking work on Gemini Man.

3D-Con ( is the 47th annual convention of the National Stereoscopic Association (NSA). It is for photographers and collectors of stereo (3D) images and anyone interested in 3D imaging including 3D movies and Virtual Reality. It will be held August 12-15, 2021
