This document summarizes a research paper about co-creation and participation as a means of innovation in new media, using photography as a case study. It discusses theories of co-creation and creativity, and how they relate to changes in the photographic field. The fieldwork findings show how amateurs have blurred lines with professionals through communities and new sharing platforms. This introduced innovations that gatekeepers like Kodak failed to recognize, focusing too much on their own services instead of changes in the field. The conclusions state that co-creation practices can challenge perspectives on creativity and innovations through collective processes rather than objects or subjects.
