The Potographic dialogues, as my previous book Dialogues while drawing, are works of art that allow me and the others to leave the limited perspective of an individual self, to enter different selves and see what does not have words, throught a combination of images. With whom I have this dialogue I look for something hidden, potential, invisible whose traces I follow from the surface, where the deep rises. The images, the photos or the drawings connect the visible traces to the invisible ones, to absent things, to desired things, as a fortunate bridge stretching on the void. The visual dialogue creates, by matching two images, a central image, a void offering a border line situation. It is both condition and and birth of every image and an image that can be almost irrepresentable. This paradoxically make it an image able to create any possible imaginary thought having several affective values according to the viever, then projected on the space. The individual can place his hown emptiness more easily than his own matter, stretching out and branching out, and the more emptiness one owns the more he can make or look at his imaginary world.
