The photography is a commitment. it is also a succession of choices: the choice of the subject, the choice of the angle of shooting, the light of the composition and the colours. These choices are the image of perception of what is beautiful to me, and what transcends the truth. Anthology of my most beautiful pictures from journeys and memories, the most striking objects or anecdotes, this book allows to think of the journey no more as the simple discovery of unknown lands, but as the only way to feel and to face other realities. The journey then becomes an inexhaustible source of enjoyment and personal enrichment. This book " colors Rainbow " is a spectrum of testimonies. Whatever is the subject, It really emphasizes the real life of this magnificent and devilish Earth. The serenpidity, is finding what we are not looking for. Just like newton who discovered gravity thanks to an apple. It is taking an image of a landscape which leads you to see something completely different, another landscape in the landscape or a form looking like an animal, an object, a face, which gives to this image embellishes another photography. Just like a search on the Web which leads you to something quite different. However we generally choose to consider that the rainbow includes some dominant colours, a determined number. This number varies from 3 to 9 according to the cultures. Aristotie used to distinguish three colours 1, Plutarch used to mention it four2. Today Western countries we generally count seven colours, as defined by Isaac Newton: Red, orange, yellow, green, blue, indigo and purple and others (Gold, Silver, Black and White, brown). The number seven was party chosen because of the analogy between light and sound, because the musical range includes seven notes by octave. it also approximately corresponds to the number of colors an average person can distinguish in the light spectrum.3
