The 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.
