17/68 Green - Red
Kren filmed, in microscopic detail the reflection and refraction of the light in/on a glass bottle. However, the bottle itself (the whole body) is never seen. What is seen is much more the emanations of light from the glass and its clarity.
Hans Scheugl: They say you were drunk when you filmed Grün - rot (Green - Red). Is that right?
Kren: I´m not sure if it was that film or not. Grün - rot was not filmed in one day, but in the course of many days. It wasn´t that easy. The whole thing was filmed in single frames while I was moving up and down. It was physically very exhausting to make this film. The lighting changes from artificial light to sunlight, which causes a change in the colors.
