In our research on the quality of ECEC settings in France, we were inspired by the 'Mosaic approach' developed by Clark and Moss to take into account the viewpoint of the children aged 2-3 years, who are welcomed in this study through the 'voice' of photography. The aim of this article is to analyse the results of the children's practices of photography, rather than the content of their photographic images. The range and diversity of children's ways of handling the camera, of how they frame their images and their roles as photographer are all analysed in as much depth as any cultural learning taking place. Through these means, this article demonstrates how to apply critical reflexivity to the methodology used for researching both on and with the children. It explains in conclusion, how our study sheds light on the challenges relating to the definition of quality in ECEC settings.
