This work focuses on an analysis of how digital natives carry out image capture, how much time is spent on this activity and what types of images are consumed in different types of social networks. It also examines what type of images are captured and what is done with these images in social networks. The study is applied to a specific sample of 93 university students who have full access to mobile devices, applications and social networks in their daily lives. It provides information as to their behavior within a changing techno-social scene which sees the emergence of new mobile devices, specialized applications and social networks dedicated to photography along with other nascent forms and styles of digital production and socialization. This shall be compared to a previous study carded out in 2010.展开更多

Nowadays Fashion Films are reinforcing the power of fashion images, building up new brand experiences for net-consumers： they are painting new worlds for fashion brands thanks to the old cinematographic language mixed to recent Internet logics. Starting from this observation, our main question was： Can we talk about a new fashion net-aesthetics for these new fashion tales？ Using a semiotics approach, this study investigates how Fashion, Cinema and the Net come together, producing new aesthetics, with new languages and new imaginary in fashion. The result can be really visionary.展开更多
