I was in Lucerne yesterday for Fat Tuesday (Gudisdienstag), which is the
last day of the Carnival (Fasnacht).
I managed to take some photos but was limited by not having a decent
flash, my only fast lens being a 50mm f1.8 (eg. 1/15s, f/1.8, iso400)
and the cold.
Here are the photos that weren't too blurred:

Yes, I know, I should try Neatimage on some of these.
