Therefore, whole sky luminance distributions representative of real-sky sectoral dynamics over short time intervals are required. A modified scientific-grade digital camera was used to measure whole-sky luminance distributions of various sky conditions. Results showed acceptable correlation between the measured and calculated results for overcast and clear skies demonstrating the viability of using hemispherical digital photography for mapping whole-sky luminance distributions. However, intermediate skies showed distinct sectoral variations and dynamics supporting the argument for more accurate and respresentative luminance distribution data.||Funding Details:||Not applicable||Type of material:||Conference Publication||Publisher:||International Solar Energy Society||Copyright (published version):||2006 the Authors||Keywords:||Sky; Fisheye; Photography; Luminance distribution; Digital photometry; Daylight design||Subject LCSH:||Sky--Maps
