Abstract

Traditional film and broadcast cameras capture the scene from a single view point while important creative parameters such as the camera position and orientation, the depth of field, and the 3D parallax when using a 3D camera rig, are burned into the footage during acquisition. To realize artistic effects such as the Matrixor the Vertigo-effect with traditional cameras is a complex task which requires skilled personnel. Within the Matrix-effect the scene itself appears frozen, while a camera movement is simulated by placing dozens of cameras in a mainly horizontal arrangement. The vertigo-effect, however, requires physical movement of the camera which is usually mounted on a dolly and translates towards and backwards from the scene while the zoom and possibly the focus are changed accordingly. Usually, the scene needs to be shot multiple times until the best combination of zoom corrections and dolly movement is found. Against this background, we present a system which allows capturing the light-field of a sequence and thus offers the full creative leeway of changing camera paths and orientation as well as setting the focal plane in post-production. In contrast to previous approaches, the handling of the involved acquisition system is compact and thus suitable for on-set operation. In this paper we describe the associated content production and present first results which underlie the suitability of the approach.
