No, I haven't used my D90 with a bubble-level tripod.
I don't mean to disagree with any of these valuable opinions that you all are giving me, but the more I think of the problem, based on the opinions I am collecting here, the more I believe that this problem has to do with the way I hold he camera looking for a reference line on the left.
Now that I have a grid on the viewfinder, I will try the center alignment, particularly when I am shooting at a wide angle.
Let me try that first, and if the problem persists, I will to the bubble level.
