Public campaigns are often organised and conducted by digitally networked Internet groups. A ‘flash mob’ is the apparently spontaneous accumulation of a crowd in a public place, where the participants do something spectacular. Other examples are to have breakfast with your neighbour in the street, a barefoot walk through the centre of town with friends, or a party in a parking space that can be rented by the hour. These campaigns must be related to the project. Therefore, they are accurately prepared and documented.
Pay attention to the shooting procedure: set up the camera, sounds, and light.
Organise and prepare goal-oriented campaigns. Clarify the roles: who is filming, who is participating, and so forth.
Often it is about spontaneity and momentum. Not every aspect can be planned, and unexpected things can happen. It is therefore also about you being open-minded.
Organise the event with the help of digital media, for example, smartphones and chats.
Resources are often free, for example, recycled materials.
Outdoor footage can be shot by a drone if permitted.
Several people can shoot from unique locations if there is enough space.
