This welding mask uses HDR video to ensure you see just how sloppy that weld was.
The creators of the MannVis augmented reality welding helmet have come up with a set of complex algorithms which allow real-time processing of HDR videos at 120 frames per second — in stereoscopic 3D, no less. The process creates an effective contrast ratio of 100,000,000:1 which is far beyond natural human capability. This incredible contrast ratio is used in an augmented reality view to show the welder inhuman detail as they weld.
