Have you ever sat in a movie theater and wondered how the projector gets an image onto the screen? It turns out there’s a lot of physics that goes into it, whether you’re using a traditional film projector, digital, or the latest laser technology. On today’s podcast, we take a look at the physics of the movie projector and how changing technologies are affecting the movie-going experience.

First we check in with Steve Seid, who, until his retirement this past December, had been the Video Curator at Berkeley’s Pacific Film Archive for 26 years. We also chat with Ryan Hufford, a Senior Systems Engineer at Vulcan, Inc., who recently installed a brand new laser projector at Seattle’s Cinerama Theatre. After many decades of relatively stable projector technology, we’re suddenly in a “tumult of innovation” as Seid calls it, and prospects for the future of movie-watching are bright and varied.
