Photovoice is a group analysis method combining photography with grassroots social action, and is commonly used in the fields of community development, public health, and education. Participants are asked to represent their communities or express their points of view by photographing scenes that highlight research themes. Common research themes may include community concerns, community assets, or health barriers and facilitators. These photographs are collaboratively interpreted, and narratives can be developed that explain how the photos highlight a particular research theme. These narratives are used to better understand the community and help plan health or social programs that address community needs.
Photovoice is often used by marginalized groups to provide insight into how they conceptualize their circumstances and their hopes for the future. As a form of community consultation, photovoice attempts to bring the perspectives of those "who lead lives that are totally different from those traditionally in control of the means of imaging the world" into the policy-making process.
