A specific number of identity portraits. These persons were chosen because of their affective proximity. They are confronted to my own eyesight, and to the necessary material for its correction. At one side, the photographied subjetcs catch a glimpse of what is my visual perception of the world. On the other side, the glasses create a modification of the model’s physiognomy during the shooting. Thanks to digital photography, I try to find out ways to create perceptions troubles by the interaction of a simple item.
