Walking shadows

One of the video clips I am working on is ‘Walking shadows’ as a result I have tried to find out the origin of shadows. The earth is exposed to the sun when it is on it’s daily rotation rising in the east and setting in the west. Shadows are the result of an interception of radiation by an opaque object between the area and the source of radiation.

Shadows are longest in the morning when the sun is close to the horizon? Which also explains the long walking shadows of my recording which I did in the morning. In the noon time you cannot see your shadow if the Sun were directly overhead because, you would be standing on your shadow. There a quite a few synonyms with shadows such as an imperfect imitation or copy. It could represent the feeling or cause of gloom or unhappiness, a dominating presence or influence, a faint indication; a foreshadowing.
