Kopal contains 1,224 Polaroids by Frank Mädler. He photographed his surroundings, neighborhood, and environment over the years, starting in 1996, until 2012, when his supply of Polaroid film ran out. Unlike his large-format images, he conceived Kopal in small pictures and cataloged them in the index in various ways - both chronologically, as they appear in the book, and alphabetically - or by quirky categories. This makes it easy to find specific images despite the variety, allowing for an interesting, self-directed journey of discovery through the book, through time, and through Frank Mädler's environment.
