Transformation of high dynamic images into virtual lighting laboratories

This  paper  demonstrates  an  image-based  lighting analysis procedure and tool called Virtual Lighting Laboratory. Virtual Lighting Laboratory  is  a computer environment, where the user has been provided with matrixes of illuminance and luminance values extracted from high dynamic range digital images. The discussions mainly refer to the flexibility of capabilities within a virtual laboratory environment to handle various lighting design and analysis problems. Conception and utilization of virtual lighting  meters  and  per-pixel  lighting  analyses  are demonstrated through architectural examples.
