“Hiroshima” (1958) and “Children of Chikuho” (1960) are photo books expressing the essence of photographer Ken DOMON. These two photo books share a common character of photographing the times. However, there are great differences in the printing quality and the book design between the two books. “Hiroshima” is a hard cover book of B4 size of good quality in all (price 2,300 yen), whereas “Children of Chikuho” is at the same level of quality and design as weekly magazines of B5 size of that time (price 100 yen). This study tried to discuss influence of such quality and design of photo books upon impression their contents make on us. We prepared a “Children of Chikuho” at the quality and design level of the “Hiroshima” and a “Hiroshima” at the level of the “Children of Chikuho”. Impression of these two photo books in addition to the original photo books was investigated by SD method. The results suggest that impression related to physical property like smoothness depends on the quality and design level but that related to the content does not.
