This is a stitched panorama of eleven individual shots of the Trevi fountain in Rome. I shot this in an arc so that I'd be able to compensate for perspective distortion in post, though I missed out on the water section of the fountain I think it worked pretty well. I'll need to remember that technique in the future when taking shots like this, which are low down and very close.
For comparison, the second shot is a single image taken at 17mm (the widest I could go) from the same spot.
The fountain was mobbed, and that was in January (low season). There were a lot of police around so I had to take great care with my gear (and my wallet) as I took their presence to be indicative of the presence of pick-pockets.
Sigma 17-50mm f/2.8 and K-3.
