Cohabitation is not an indicator of love in each other, far more important is how you share a bed with your other half. Is it normal for couples to sleep on opposite sides of the bed or the arms of sleep — that's the key to normal relations? To these and other questions tried to answer Viennese photographer Paul Schneggenburger, removing the sleeping couple in their bedroom Studio. Placing lovers on black bed linen and turning the lights on the Christmas tree, the photographer exposed 6-hour exposure in the camera, which worked from midnight to 6am. Us the results of these studies will be to determine which of the couples love each other more than others.
