Edible landscape: yellow oasis. Edible landscape. Carl Warner is a photographer who worked in advertising for many years. After years of work, however, he searched for new inspirations until one day at the market he saw mushrooms that reminded him of trees from the world of strangers. In this way he created his first edible landscape, and with it a new direction of his career. The series of his works is called Foodscapes and it is a combination of food and landscape words.
