The Yokohama Civic Gallery Azamino holds an annual exhibition entitled "Azamino Photo Annual" that captures the current state of photographic expression and the Yokohama City Camera and Photo Collection Exhibition. At the 2020 collection exhibition, we will introduce about 150 collections with the theme of photography and print. Photograph printing technology has also influenced photographic applications, subject selection and expression. The main subject of the daguerreotype, the first photographic technique announced in 1839, was a person, which could not be reprinted, so the photo was owned by the person in the picture or someone close to him. The negative-positive printing technology has evolved in place of the daguerreotype. In 1851, when a collodion wet plate photograph was released to obtain high-quality negatives, multiple paper-baked portraits created from a single negative, and commercial prints of celebrities and famous places were produced. It will be like. Throughout the latter half of the 19th century, new paper-baking printing technologies were developed one after another, including photographic paper and albumen print, which were the mainstream at the time, in order to produce higher image quality, color choices, ease of use and durable photographs. It has been done. When halftone printing was invented in the 1880s and it became possible to print a large number of photographs made with letters on a printing press, photographs of social events were used for mass communication as plates for magazines and newspapers. It will be so. On the other hand, in the 20th century, for photographers who aspired to photograph as works of art, which technique to choose for each photograph became an important factor in establishing expression. In this exhibition, we will explore the relationship between print and photographic expression through photographs produced by various techniques of the 19th and 20th centuries, and closely related cameras and materials.
