Infra mince is a term used by Marcel Duchamp to describe perceptions so tiny you can barely see, feel and repair. This book is divided in two parts, each of them contains two smaller books in with a sequence of photographs of nature phenomenon that we have seen frequently but not repair on the sequence that does´t stop because of time. Like a water fall that converts water into breeze or a wave that leaves a mark in the sand, or the light that leaves a reflections which is really does´t exist. The form of the book also has a sequence way of reading it.
