Time Out says
Located in the corner of a sleek, black building, Mulnamoo (literally meaning “water tree”) is made up of a studio on one side and a store on the other. The store sells traditional Korean handicrafts and the studio specializes in black and white photography. One of the most popular options is to take an 8x4 photo framed by a gray mat. The 200,000 won process involves two months of picking out prints in order to receive the framed final product at the end. However, those seeking something faster and more wallet-friendly may choose to have a black and white Polaroid taken for 30,000 won with specially imported Fuji film.
