The Palace of the Dukes of Braganca was built in 1420. It is the most impressive historical building in the town of Guimaraes, near Oporto in Northern Portugal. Its most prominent features are these towering circular brick chimneys, once used to vent the many fireplaces in this huge, fortress-like building. The best way to emphasize this array of towering chimneys is to abstract the building by shooting only a part of it, and much of that in backlit silhouette. Using a 24mm wideangle converter lens on my Canon G5, I take a low vantage point and shot up into clouds. I use my spot meter to expose for the white clouds. The sky becomes a deeper blue, and that part of the palace that is in shadow goes black. This abstraction forces the eye of the viewer to the thrusting chimneys and on up into the clouds. It does not take a great leap of imagination to see the column of clouds in the center of the picture become a column of fireplace smoke, either.
