To photograph, store, and organize the art work of the painter, Andrew Wyeth in Chadds Ford, Pennsylvania, in 1987 Fred Mintzer, Henry Gladney and colleagues at IBM developed a high resolution digital camera for photographing art works and a PC-based database system to store and index the images. The system was used by Wyeth's staff to photograph, store, and organize about 10,000 images. "Pictures were scanned at a spatial resolution of 2500 by 3000 pixels and a color depth of 24 bits-per-pixel, and were color calibrated." This was the first digital image database of cultural materials.
