We were shooting chronologically in order to leave room for adjustments to the script in case anything unexpected happens. Although there was a very specific concept for the image and sound, we stayed as flexible as possible. There were various locations for each scene, so we could decide spontaneously in case a certain spot was too hectic or dangerous.
In order to get disrupted as little as possible during the shoot, we had to blend in. Meaning: costumes for everyone. The equipment was hidden, there was no clapperboard, no loud instructions. We communicated via radio, which was discreet and practical amidst the surrounding noise. The camera was close to the actors in the crowd, while the rest of the crew was scattered all around. I had a wireless monitor and audio output to be able to whisper instructions into the DOP's ear during the take. Nice!
