Challenge #1:Arranged

I titled this shot 'Organized Crime'.  This is a shot of a new sculpture (?) in Calgary's Olympic Plaza.  Each pole in the sculpture represents a park in our City.  The older the park, the taller the pole.  The old sandstone building in the background is Calgary's old City Hall. 

This pic was shot on an overcast day with a flat sky.  The 'as shot' image was full of converging lines; the poles on the outer edge of the frame were leaning towards the center of the image.  I used a lens distortion filter in Photoshop to correct the convergence and straighten out the poles.  There's still some slight convergence to the image, but not as severe as it was in the original.

A point to note: This was shot at 12:50 on a Monday afternoon.  It was rather odd that I was able to get a shot like this without any traffic or pedestrians in the frame at that time of day in a very busy part of the city.  Timing is everything!
