An IT8 target is based on an International Standard ISO 12641 for color management. The IT8 target contains color patches organized in 12 rows by 22 columns, plus a neutral scale at the bottom. The IT8 target is designed for devices such as scanners and printers, but not digital cameras. As an alternative, LaserSoft Imaging created the SilverFast DC Pro target that calibrates the digital camera. This camera profile acts as a reference for future shots in the same lighting conditions, with the white balance, ISO setting and other camera settings set to the same values.
