One aspect of photography a lot of photographers seem to miss is what one sees when one looks straight up.
This is the ceiling, staircase and mezzanine of the Canadian Museum of History in Gatineau, Quebec (on the other side of the Ottawa River from Ottawa, Canada).
I've updated the first shot with three more images taken the same way, but I moved around and used different focal lengths.
