A week ago I was in Cannes on a business trip. While there I took a few shots and this panorama. The original is 30,000 pixels wide (after resizing for print at 24 x 100 inches) and made up of 9 DP2M images.
The linked image is therefore 10% of the actual image size.
The original shots were all handheld, manual settings, and stitched in PTGui
