Datacolor Spyder Cube

Comparing the original to the two images, the JPEG is remarkably close although it does tend towards a very slightly green hue. The SpyderCube version is actually noticeably more accurate, with the yellows in particular being significantly closer to the actual book cover. For many purposes the JPEG is close enough, but if a high degree of colour accuracy is required then the adjusted RAW capture is noticeably better. There is no doubt that the SpyderCube performs as intended, quickly and simply offering accurate results. Recommended.
