Aperture

Inspired by human eye`s iris and irises in camera objectives, the installation called Aperture consists of a matrix of iris diaphragms reacting to light.

Aperture is a facade installation with interactive and narrative displaying modes. Consisting of an iris diaphragm matrix, the facade's surface with its apertures' variable opening diameters is enriched by a dynamic translucency, that creates new imagery as well as a new channel for communication between inside and outside.

An iris diaphragm is an aperture with a variable opening diameter. The majority of instances of irises can be found in aperture settings in camera lenses as a means of regulating depth of field and the amount of light that is exposed by either film or sensor in capturing an image. Aperture, being an array of irises, is part of a building's facade.

Composed of single aperture-modules with receptor (LDR—light dependent resistor) and actuator (servo-motor/iris), Aperture acts like an autonomous skin, which is also capable of precise external control. Visual information is transmitted from the inside of the building to the outside, the surface permeability is regulated when the aperture's opening diameters are changed. Each of the apertures in the array can be used to represent a pixel of an image.

Set to interactive mode, each single aperture and all the apertures as entity "see" what happens on the inside of the facade and react accordingly: like the human eye's iris and irises in objectives, they react to light, widening and contracting with corresponding increases and decreases in intensity of incoming light. If no human activity is to be distinguished on the inside, a "memory" mode recalls images and abstract animations captured throughout the day and displays them.
