The SpyderCUBE RAW Calibration Tool from Datacolor is a compact (1.5"/3.8 cm square), digital color balancing tool that not only allows you to correct the color temperature but also the exposure, brightness and black point of your images. The SpyderCUBE is a spectrally neutral three-dimensional tool that's small enough to fit in your pocket or camera bag and gives you all the features needed to easily adjust your images in post-production. Its multi-sided construction allows special attention to highlights and shadows, and contains more features for image control than a gray card or white balance tool.
