I took this shot in the Summer of 2009 during the Kitchener Blues Festival. The reflecting pond water feature outside of city hall had been drained and a beer tent set up. Unfortunately there had just been a torrential downpour, flooding the pond. The surface is very flat and level (since it is also used as an outdoor rink in the winter) giving the water not much place to go. A group of people armed with squeegees started pushing the water away from the beer tent. I caught these two taking a break, where the smooth still water was incredibly reflective.
This was shot with the Pentax K20D and Sigma 24-60mm f/2.8 at 1/50s f/8 ISO 400. Yes, there is a bit of Photoshop to remove a few unwanted objects.
