The Application of Computer Graphics in Lighting Design

Photographic tone reproduction for digital images

“…There are comparisons possible with many other techniques that are outside the scope of this evaluation. In particular, we do not compare our results with the first perceptually-driven works [Miller et al 1984;Upstill 1985] because they are not widely used in graphics and are similar to works we do compare with [Ward 1994;Ferwerda et al 1996;. We also do not compare with the multiscale-Retinex work because it is reminiscent of Pattanaik's local adaptation model, while being aimed at much lower contrast reductions of about 5:1 [Rahman et al 1996].…”

Adaptive Logarithmic Mapping For Displaying High Contrast Scenes

“…Clearly, proper capture of luminance (radiance) and chroma for any environment requires higher precision than offered by a 24-bit RGB representation. This fact has been early recognized by the lighting simulation 8 and physically based rendering 16,20 communities. As a result of lighting computation, luminance values in the scene are reconstructed and rendered images are saved using file formats capable of representing the complete visible spectrum 19,6,5 .…”

“…Mainstream imaging and rendering software are now addressingthe need to represent physically accurate lightinginformation in the form of high dynamic range (HDR) textures,environment maps, light fields, and images in order tocapture accurate scene appearance. Clearly, proper captureof luminance (radiance) and chroma for any environment requireshigher precision than offered by a 24‐bit RGB representation.This fact has been early recognized by the lightingsimulation 8 and physically based rendering 16 , 20 communities.As a result of lighting computation, luminance valuesin the scene are reconstructed and rendered images aresaved using file formats capable of representing the completevisible spectrum 19 , 6 , 5 . The same formats are used forhigh dynamic range imaging 2 , where photographs of a staticscene taken at different exposures are assembled and savedin a radiance map (Figure 1).…”

The high dynamic range imaging pipeline : Tone-mapping, distribution, and single-exposure reconstruction

“…In the 1980s there were attempts at matching the appearance between a real-world scene and an image displayed on a screen [184,249]. In the early 1990s, the problem was formally introduced in the computer graphics community [241], for the purpose of displaying images generated by physically based rendering methods.…”
