xinerama

Xinerama is a term that refers to a type of widescreen film projection technology. It is characterized by a very wide aspect ratio, typically around 2.5:1 or 2.35:1, which provides a more immersive viewing experience compared to standard aspect ratios. The name "Xinerama" itself is derived from the Greek word "xenos," meaning foreign, and "orama," meaning sight or view, suggesting a broad and encompassing visual panorama.

The technology often employs a multi-projector system, though modern iterations can achieve similar wide aspect ratios with single projectors and anamorphic lenses. These lenses squeeze the image horizontally during filming, and then unsqueeze it during projection, effectively creating a wider image on a specially designed screen. The wider field of view captured by Xinerama allows filmmakers to present grand landscapes, expansive action sequences, and a greater sense of scale. Early uses of Xinerama were often associated with documentaries and epics, aiming to showcase the grandeur of their subjects. While not as prevalent as other widescreen formats, Xinerama continues to be a choice for filmmakers seeking a distinctively broad visual canvas.
