In somber, chemical cerulean and silver, Michael Koerner’s work hearkens to an early method of photographic development and to his own family history; his mother survived the bombing of Nagasaki as a child, and Koerner is the sole survivor of his immediate family, the others having succumbed to cancer and genetic disorders. Koerner’s experiences serve as a reminder to his audience of the continuing fallout from such a nuclear option. His stunning tintype prints present eerie reactive clouds and crystalline formations produced by collodion on tin.
