Think about the last great photograph you took. It might be a landscape you stood in for 20 minutes waiting for the light, a street scene that captured a split second of urban choreography, or a portrait where everything (expression, light, background) just clicked into place.
Now imagine being able to step inside it: to move your head and sense the depth that was there when you pressed the shutter. To experience the image not as a flat rectangle on a screen, but as something you can look around inside.
