We photographed luminosity of the setting Sun at Brahmaputra River by three powerful digital SLR cameras on January 26, 2014 with a view to compare the intensity ratios of the luminosity of the setting Sun using the photometry principle and the Rayleigh scattering theory. The results exhibit a significant deviation in the calculated intensity ratios, suggesting further investigation in this direction.
