In this Thesis I examine the alternation between different types of perceptions. This research is the point of convergence of 3 reflections: Reflection on the moving image, and more precisely its genesis: the optical illusion. Reflections on my graphic design tools. How can I produce with them, experiment with them, and consider them not only as a mere user? This reflection is directly linked to a world of work that is today globally digital and for my part a desire to have a more sensitive approach with these tools. And finally a reflection on how to share my research, my processes by inviting the spectators to live my experiments.

During the layout of this thesis, my choices were dictated by the desire to interrogate the viewer's perception directly. The embossing of the title in the mirror paper sends back a distorted reality to the reader. The Riso impression allows to question the imaginary behind the printing process and to highlight particular mechanical qualities. I also inserted between each part of the Thesis some transition pages composed of semi-transparent sheets where are printed flat tints of bitmapped colours.
