This broken window in on old factory building intrigued me, but I didn't know why. I took the shot and then noticed that there was no reason for the bright blue in the window except that the glass was reflecting the crystal clear blue sky -- except for the missing pane. OK, so maybe not a reason for deep, thoughtful fascination, but think how easy I must be to keep entertained -- sort of like a border collie on a road trip. :-)
I also tried applying the PS cutout filter, but the effect probably isn't as obvious except at full size (which I haven't posted).
