Note to readers: this is an excerpt of an essay I wrote for the artist elin O'Hara slavick (This is the Japanese translation; the original Englisversion is also online—see below.) She chose objects that had been exposed to the nuclear explosion at Hiroshima, and made cyanotypes My essay is about what is visible, and what is not visible, given the many kinds of radiation to which these objects were exposed The original book (which is beautiful, and has much wider margins than the ones in this document) is available here: daylightbooks.org/store/ elin-ohara-slavickafter-hiroshima This excerpt was originally posted, in English and Japanese, here: saic.academia.edu/JElkins Because of copyright, the end of the essay is omitted i i i i iii iv v i i iii i 1
