Tourists atop St Pauls
[FZ20: 1/1000, f5.6, ISO80]

Cropped. sharpened and corrected the colour/contrast/brightness slightly. You can't really make out the tourists without looking at the larger version of the image. Clicking on any of the photo entries brings up a bigger view of the picture, in case anyone actually reading this site hadn't figured that out yet! :o)
