Simple rules really.
1. No cooked foods, or preservatives.
2. No plastic packaged food.
3. Traditional markets and supermarkets are allowed, as long as the food is the main focal point of the work.
4. Try to avoid price tags, as they do nothing to enhance the food. Best to crop them out or get rid of them by cloning or some other means. Pictures with price tags may be displayed, but will not be featured.
5. No blood and gore!
6. No people in the pictures, unless they are very inconspicuous.
