My study is in the line with Aesthetic. Its objects is the study of the impact o media in the process of aethtetic creativity and developpement of sensitivity. In France, social sciences are state-of-the art in that field. Aesthetic, a human science, experiences more difficulties. Although, it is legally the best placed to mention taste and setting up of narrative and experimentation issues. Since 2004, i am interrested into mobile images. Those wich are on the Internet but those cinematographic, on TV or amateur wich go from movie theatre to homes and on screens of mobile objects. In France, there is either contreversy nor debate on that change of works'statuts, on the issue of images and sounds'quality. What happening to still photographie or the work on the lence when one movie is digitilazed in low resolution ? I can remember in the 70' and 80', the important aesthetic contreversy on the issue of having movies on television. At the end of the 80', the famous movie critic Serge Daney annoyed by some critics and movie maker'contempt. Serge Daney decided to give a daily chronicle in the french newspaper Liberation. Named « some movies on tv », that chronicle delt with explaining the change in the status of perception of movies broadcasted on tv. He liked to « venture into describing it » : « In short, one has to experience it, that's is to say, generations to come will discover cinema through its loss ». One period was over, and one has to thyink about the changing to another, the cohesion of two periods of time. Thus next question is : in a context of digitalised datas, a streaming intense and excessive of images and sounds, witch sensitivity is at work ? What about this still new sensitivity appearing in young generations entering in a world where datas are shared, apparently free, downloadable, copiable… With out any conscious that this world is only in fact accessible by paying an entrance and exit right. One uses generaly this expression Low resolution (in french basse défibition) to discribe the quality of images coming from the technic of data compression.
