Anniversary poster for the Zwicker AG Licht. A poster has been created that pays tribute to the creative and differentiated use of light. A physical phenomenon called the “shadow blister effect” is used to visualise the theme. This effect was captured photographically and then inverted to bring the subject of light more into focus. Physical phenomena have fascinated both of us for a long time. Light dominates our perception. For this reason, it was obvious that we would resort to the physical phenomenon of the “shadow blister effect” and deal with it in more detail. In collaboration with David Zwicker.
