A photographic technique with a history of more than 180 years that uses silver halide as the photosensitive material for photographic film and photographic paper. When the photographic paper is irradiated with light through the negative, the silver halide coated on the paper reacts chemically to produce colors, and the image emerges.

HIRAOKA SHOKO, the author of the photographs, produced the entire project, including the framing for each photograph. The frames are made by LapiArts, a framing specialty store. The frames are handmade one by one.
