Mobile phones with an integrated camera have made the accessibility of photography as a medium for capturing everyday life more accessible and used than ever before. The technical quality of integrated cameras in mobile phones today enables technically high-quality captured photography, which is an ideal opportunity to create quality photographic images of the gastronomic offer and environment, while maintaining the syntactic and semantic characteristics of photography. The internet connection of mobile phones, the possibility of using social networks directly from the location, the automatic connection of the file with the location and the possibility of presenting photos create additional possibilities for interactive promotion of gastronomy. The photographic promotion of gastronomy is based on food photography that has evolved from the very beginnings of photography as a medium. However, it is the advent of smartphones with a built-in high-quality camera that is leading to new approaches and aspects of food photography.The diploma thesis theoretically analyzes the development of food photography in the context of the development of photography and, in particular, in the context of the development of a digital photographic system and the integration of a camera and a smart mobile device. The central part of the thesis consists of author's photographs of food taken with a camera integrated with a smartphone as part of the promotion of gastronomy.
