We describe the design of a very high resolution, low-cost scan camera for use in image-based modeling and rendering, cultural heritage projects, and professional digital photography. Our camera can acquire black&white, color, and near-infrared images with a resolution of over 122 million pixels and can be readily built from off-the-shelf components for less than $1200. We discuss the construction of the system as well as color calibration and noise removal. Finally, we obtain quantitative measurements of the light sensitivity and the optical resolution of our camera and compare the image quality to a commercial digital SLR camera.
