Thanks.
All of the shots are just scaled down to web-/flickr-size and/or cropped into a square. But none are really partial crops or anything.
I don't know if the reason for rather tight crops was alcohol, but looking at the pics from the weekend there was a tendency to go closer and closer as the day went on...
Anyway, the best thing about rock-festivals is that people are always on good mood (or drunk) and thus always more than willing to strike a pose for anyone and especially for a person who's carrying a "big camera".
