Again, this is the Danforth area of Toronto. Note the differences between the photo above and the photo below. The shot above was taken with the polariser spun to be at its minimum effect. The one below was taken with the polariser spun about 90o or so, to give its greatest effect. Note how the windshield in the image below is transparent, and the windows of the buildings across the street much brighter. Not sure how the two fellow in the foreground vanished so quickly (perhaps they were a reflection themselves).
