For your info: There is an article in the most recent edition of Sky and Telescope magazine about "photographing the analemma".
It describes how photos have been taken which show the movement of the sun. They rely on time lapse (either 365 or 12 exposures over the course of a year), with each exposure taken at the same clock time each day. The photos are of a landscape including the sun itself rather than a shadow thrown by it. Apparently, only 5 such photos are know to have been produced. The article also mentions a web site at http://www.analemma.com which provides a very clear explanation of the analemma and its consequences. Steve
