Abstract
Prospective outdoor imaging depends on diurnal changes through the day and it needs an understanding of light and its effects on quality of the images. In this paper, investigations have been carried out to study the effect of diurnal changes on the quality of the images taken at regular intervals of one hour from sunrise to sunset in a sunny day. For investigating the effect of sun orientation, the images were also taken in four different directions i.e. East, West, North, and South. The analysis of the results showed that the picture quality varies with respect to time and the orientation.
