This handbook provides guidelines on the practice and ethics of participatory visual methods (PVM) with emphasis on their use in low- and middle-income countries (LMIC) for community and public engagement in health and health science. The guidelines are drawn from the experience of the authors, gained through working with these methodologies for over a decade. The handbook has been developed for use by engagement practitioners who are relatively new to the field of PVM and want to learn more about how to work with them. It also aims to support health scientists who wish to include visual methods when engaging local communities and wider publics in their work. For each method that is described the pioneering work in the field is cited, along with other suggested reading, should you wish to learn more. The content of this handbook is also available as an online course on The Global Health Network site.
