The word "selfie", which appeared in the early 2000s, made the headlines when it was labelled 'word of the year' in 2013 by Oxford dictionaries, and it entered the French dictionary Le Petit Robert in 2016. As Tifentale argues, selfies are "a hybrid phenomenon that merges the aesthetics of the photographic self-portraiture with the social function of online interpersonal communication" (76). These self-portraits, usually taken on smartphones as snapshots and usually carefully staged, are meant to be shared and repurposed: the same image stored in a hard drive and never posted online would not be a selfie. Selfies, as cultural phenomena, conflate three very distinct types of activity and representation: they pose as the latest avatars of a long tradition of self-portraits; they rely on a set of technologies (digital photography, tagging, editing, posting) embedded in smartphones; they constitute a key component of social media practices where they are massively posted and shared. Art and technology and mass consumption, all in one. In the series Perfect Skin (2007-2020), the French Canadian artist Gregory Chatonsky repurposed the massive dataset of selfies posted by a global celebrity, Kim Kardashian, through a specific generative algorithm to create disturbing decompositions of her figure. This artistic gesture combines two provocations in one: by relying on a machine to produce new images, he undermines the collective representation of the artist as an author; by repurposing images from a disreputable genre, criticized for its narcissism, voyeurism and vacuity, into a form of conceptual art, he blurs the distinction between art and mass media.2 Chatonsky provides several philosophical and artistic references as the general framework of his project, with a special emphasis on the notion of self-design he took up from Boris Groys. In Going Public, Boris Groys argues that: It could even be said that self-design is a practice that unites artist and audience alike in the most radical way: though not everyone produces artworks, everyone is an artwork. At the same time, everyone is expected to be his or her own author. Now, every kind of design -including self-design -is primarily regarded by the spectator not as a way to reveal things, but as a way to hide them. (np))
