summary In this paper, we present a user-friendly and practical method for seamless integration of computergeneratedimages (CG) with real photographs and video. In general, such seamless integration isextremely difficult and requires recovery of real-world information to simulate the same environment forboth CG and real objects. This real-world information includes camera positions and parameters,shapes, material properties, and motion of real objects. Among these, one of the most important islighting.Image-based lighting that is developed to recover illumination information of the real world fromphotographs has recently become popular in computer graphics. In this paper we present a practicalimage-based lighting method that is based on a simple and easily constructable device: a square platewith a cylindrical stick. We have developed a user-guided system to approximately recover illuminationinformation (i.e. orientations, colors, and intensities of light sources) from a photograph of this device.Our approach also helps to recover surface colors of real objects based on reconstructed lightinginformation.
