I cut prints of my own photos, taken since 1989, into pieces of 1 x 1 cm by hand. This action is part of the work "ZWISCHEN ERINNERN UND VERGESSEN" (Between remembering and forgetting) - see also performance. For "sur la structure de l'image / de la perception" a section of these photo pieces is pasted on 12 multiplex panels of 120 x 180 cm each in random order. The 12 panels correspond to a 135 mm film with 12 pictures on a scale of 50 : 1. The distance between the panels is in approximate accordance with the distance between the pictures on a 135 mm film (50 : 1). The wall for presenting the panels should therefore be 25 m long. Alternatively a presentation in two groups (of 6 panels each) or three groups (of 4 panels each) is possible. This would correspond to the standard size of developed negative strips in Germany, France and Japan. All 12 panels should be exposed together.
