New book on aquatic structures called Dolphin. Once again we are amazed at the quality expressed by Hannibal's photographs. A succession of emotions contained in the shots, a fantasy of incredible whites and blacks: in short, the quality standard is always high. Hannibal has been spoiling us for years. It seems almost to be reflected in these fantastic light dark. Unfortunately we can be in those places only with the imagination, but with the certainty that if we visit them one day we would not find them as beautiful as we admire them in these pages.
