Gretag-Macbeth card shot with Canon 10D in blue-sky shade, incident-metered for ISO 100 and camera set to ISO 100 in manual mode. This is the RAW data, with each channel interpolated to full image size and then downscaled to 800*533, with levels scaled so 0 to 4095 becomes 0 to 255. It is still linear and not white-balanced.

other sizes: small medium original auto
