I heard the word virtual used to describe the camera, and couldn't figure out if they were, for sure, talking about taking pictures of a single photon in real life -- ergo not simulated.  I suspect I misunderstood something.<p>I'm skeptical because.. how would you see a photon? Unless photons themselves give off light as they travel, but that would mean photons emit photons...
