Qualitative research extensively utilises interviews to gain insight into the intricacy and texture of lived experience. However, there is growing recognition of the limitations of interviewing as a data-gathering method. Popular alternatives include a move to visual methods, such as photo-production, to enhance the interviewing process. In this article, we argue for the power of materiality in this process. We propose that material objects, such as photographs, items of clothing, and personal journals, have power to simultaneously provide proof of the past, produce increased narrative depth, force change in narratives, and change the interview process and the relationships caught up within it. We illustrate these issues by drawing on data from a research project about weight loss. We conclude by considering the implications and value of using material things in research.
