The human eye has the capability of seeing a wide range of luminances in any single gaze. This is because the eye is continually re-focussing as it sweeps the scene. High dynamic range imaging or HDRI or HDI, is exactly the same principle, applied to photography, or synthetic environments. Many different render passes, or photographs with different exposure times are taken, and combined into a single image of crystal clarity, far more realistic than a camera is capable of taking in any single frame.

These images are often then used to generate digital luminosity maps, that are translated directly into synthetic environments to guide lighting levels.
