How to grasp the dynamic of ambiance in order to understand and design urban publics spaces? In a recent PhD research (Filmic apparatus & Urban Landscape), I question the role of filmic apparatus in the understanding of the ordinary transformation of places. If the filmic medium itself, as well as filmic practices, can underline the on-going relationship between space and acting and perceiving bodies (i.e. the ordinary transformation), this communication will focus on the filmic reception, where a film can be considered as an intermediate object helping to built a collective understanding of a place and its ambiance. We believe that it is by sharing different perceptions of a place - tinted by the different practices that people can have within it - that it is possible to grasp its complexity. We will discuss a method through which different actors are building upon their own sensitive experiences (re)activated by a shared reception of a film. In that context, the film is not only considered as a mean of representation, but also as presentation. It is through the presentation of the sensory aspect of a place and its ambiance that a fruitful conversation can happen and expose different (nay divergent) points of view, from which a collective creativity can occur. To widen the reflection on the role of intermediate objects leading to the collective understanding of ambiance, we will introduce an on-going research (Auscultate the Environment) where it is not film but sound recordings that are the base for discussion.
