CaptainJack1,

  Thanks for your explanation.  I knew some of this but your description helped to fill in the gaps.  Very well done!

   So, to do a silhouette, do I need to do it the "real world" way?   By adding a transparent plane between the object and the camera?  Will that work?  Is there a better way?  I was hoping to be able to do some animation with the shadowed character.

  Thanks again for everyones input!
