The pictures were taken on almost square instant film and later trimmed to the 35mm film format. The book pairs Daido Moriyama's images with a selection of the essays he has written over more than forty years, since his youth. The title comes from a remark of his: even if photographic paper and developing fluid disappeared, he would not care, because he would go to the supermarket to buy eggs and vinegar and make cyanotype prints in the sunlight with the white and the vinegar. Quiet dark interiors and details appear between the written pages in muted black and white.
