What is photography without, uh, photographs? Nada? Nil? Null? Beyond images, photography is possibly something else because it is, after all, abstract. Mishka Henner creates a wordily picturesque elaboration of what Photography Is, a book in which he connotes and denotes, in thousands of ways, the most dexterous and universal form of photography. Included in Henner’s From Here On exhibit last year, this definitive compendium contains 189 pages of ‘chaotic and insightful’ phrases and snippets that define what photography really is.
