Images have the power to influence people and laws define what is appropriate to photograph in public and private spaces. Photographers' rights, public property rights, and requiring models' consent are issues addressed by legislation. New technologies enable quick and easy distribution of images on social media, sometimes without subjects' consent, and research examines voyeurism, surveillance, and professional photojournalism standards regarding distributing photos of others. Potential case studies could analyze photos of a Syrian child or Princess Diana.
