What makes realistic video?


3D? Nice! High dyanmic range (HDR) imaging? Great! Any thoughts on 3D HDR?

Stereoscopic 3D technology.


Aiming at real-life experience.

High dynamic range imaging.


Struggling to determine a correct exposure? It is time to consider HDR.

Living in a digitized world.
