Instinct is traditionally abstract and intangible. Some people have a natural inclination to trust theirs. Others must cultivate the relationship. Many, instead, opt to borrow it from friends, family or colleagues. But Instinct now comes in a convenient and palpable new physical form — a book. Instinct is my new photography monograph — a collection of 70 "street" photographs, culled from a two-year, pavement-pounding, photographic examination of humans simply being.
