The article discusses the specifics of street photography realized in museums and galleries. The author focuses primarily on issues related to how the museum space inspires street photographers, affects the way they choose the frame or subject matter of the photo. Photographing in the museum is undoubtedly a challenge, first of all, for technical reasons: low lighting, which forces you to work for longer shutter speed, using a tripod, or, for example, problems related to choosing the right values for white balance; it is also often associated with work in a crowd of visitors, the need to respect the rules for taking photos, various for various museums, as well as facing architectural barriers - all these factors determine the nature of the frames made in the museums or galleries. The author puts forward the thesis that street photo as a photographic practice implemented in a museum, strictly dependent on technical limitations imposed by the exhibition space, uses its own, specific "code' or set of tricks, slightly different from what can be found in works made strictly on the streets. On the example of selected photographic projects (long-term cycles by Elliott Erwitt, Alécia de Andrade, James A. Hudson, Stefan Draschan) and photographs of, among others, Henri Cartier-Bresson and Vivian Maier, the article discusses the most characteristic features of photos that can be classified as street photo made in museums. These include: the focus of photographers on the reaction of the protagonists of photographs to works of art, attempts by photographers to create specific "catalogs of behavior' for museum guests, resignation from games of light and shadow which are specific for street photography, conscious use of elements of museum architecture as elements of frame. The reinterpretation of the conventional language of street photography by photographers working in museums and galleries makes it possible to see in the "museum' variety of street photo a separate phenomenon in the history of photography.
