Food photography is about much more than beautifully presented dishes in cookbooks - it’s also being used to change the way we think about what we eat.

Emily Thomas meets three photographers to discuss some of their most powerful images - from a bloody scene in a Thai slaughterhouse to a display of human resilience in a refugee camp.

They explore why still images of food and food production can be a compelling way to communicate about politics, society, and economics. We also hear about the impact such hard-hitting photography can have on the people behind the lens.
