In 1901, Émile Zola, who was an amateur photographer, said: "In my view you cannot claim to have seen something until you have photographed it." Frequently, we discover details in a photograph, that we did not see when we took the picture. And what about photographs showing small worlds, such as wild flowers? Through the selective use of the camera, the photographer can focus his vision on sometimes baffling details of those small worlds: Shapes and colors are here translated by grey values, bizarre petals, perfect geometries. And behold the small worlds that transfigure in large universes.
