I'm a bit behind on the blog, but to tide you over here's two pictures that capture the festival for me:
1) The main tent at quarter past midnight on Sunday night, just after the last act...
2) The same angle from the same spot, just before noon the next day.
Note that I didn't have any form of artificial lighting for the first picture; no flash, no streetlights. They don't call it the land of the "Midnight Sun" for nothing!
