If the goal is photo-realism on Earth in daylight with few clouds you
would need to add the scattered light contribution. The scattering
factor is dependent on the wave length of light, thus blue light is
scattered most and will soften a distinct shadow, as well as make it
You could use a 3D rendering program to capture jpg's of various
shadows if you wanted to. Most any will accurately render the effect
of sun, sky, ambient light, and radiosity. Some even have algorithms
for longitude, latitude, time of day, time of year to capture the
correct sun conditions anywhere on the globe, such as Cheetah 3D.
On the moon or other planet without atmosphere or clouds, there would
be no reflection or scattering, thus long shadows remain distinct.
