In 1975, four people politically involved on the left planned to create a photographic agency to provide images and posters related to the political movements of the time. Faced with the difficulty of being able to make a living from it, two people quickly left the group, but were quickly replaced by other photo enthusiasts. A militant photography agency was born: Interfoto, whose members were all activists in various capacities in organizations: trade unions, neighbourhood groups, solidarity groups with immigrant workers, feminist and Third World movements. Left-wing movements whose objectives were to transform society. The personal involvement in these groups allowed Interfoto photographers to gain confidence with the struggling organizations during the shooting.

Interfoto photographers have chosen not to focus on author photography, but on the contrary on collective creation. Ideally, it is in teams that they determine the reports to be made, that they decide on the photos to be distributed, that they divide up the tasks without hierarchy or specialization. It is according to the availability of each one that they carry out the shooting, the laboratory work, the archiving and administration, the construction of exhibitions and books.
