This is how students take over the city of Kraków each May!
Shot on Canon 60d with Sigma 30mm 1,4 and Tokina 11-16mm 2,8. Mostly shot at f. 16-22 due to very strong light and lack of ND filters. Another minor hindrance was the fact that I had my 9-month-old daughter in a baby carrier on my chest. She had fun, too, and even managed to get some sleep. Atta girl!
Sound was recorded through Rode Videomic with levels set manually down to almost zero due to enormous noise around.
I used a Benro monopod with Manfrotto 701 head (also for the overhead shots).
