I returned from my family visit in Ottawa. There was not much time for photography but I did get a chance to see a very good exhibition at the National gallery called "Made in America". If you are in Ottawa or planning to visit there in the next two weeks go and see the exhibition. It is very good. Of course I love the building and every time I can't resist taking some images. I raised the contrast to to enhance the light and shadow patterns. The result is a dynamic black and white abstract image.
