The exhibition’s theme does not end with Aleksandra Vajd and Hynek Alt’s project, but it evolves further in Bára Mrázková’s work called external surrounding membrane, internal core layer, external plexiform layer, internal core layer, which takes us with its name alone to a land of observation where the viewing function connects with the function of understanding. This is how we know it from the English double-meaning of the phrase “I see” (I know). With her installation Bára Mrázková places us right on the spot of the border between the cave and the external world, in the moment of fierce blinding, when we lose contact with the past (according to Plato through a world of senses, illusions, shadow-play and doxies) unable to read the world of logos, epistemes. On the retina burned by a sun spot it allows us to see the world behind us. The simple and exact manifestation, justas symbolic as a commenting photographic and scientific principles, focuses on the phenomenon of light as such; light as a condition for life and sight and photography. The counter-light again speaks to the nature of media and its processes, of flash inthe eyes, of the moment when you come out of the darkroom. When we turn away afterwards, we block the light projected onto the world with our own presence. The reduced visibility covers up other content and terms. We are alone with ourselves, inside, and we attempt that strong experience, stifling the state of ecstasy by the quickest orientation in space possible. Control equals surviving and choosing theright shield.
