Analyses of remote-sensing imagery from a fractal perspective have bec
ome more frequent in the literature. However, one aspect which has not
been considered specifically is how images integrate a mix of several
, possibly very different, fractal processes. In this exploratory inve
stigation, the fractal dimensions of sunlit and shadowed areas of surf
aces of known fractal dimensions were determined. It was found that th
e shadowed areas tend to have fractal dimensions approaching 2.0, wher
eas, surprisingly, sunlit areas have fractal dimensions which are inve
rsely related to the fractal dimension of the surface
