Datacolor offers its line of Spyder4 colorimeters for calibrating monitors, laptops, projectors and other devices for accurate and consistent color correction. A seven-channel sensor registers color in the same way as the human eye, ensuring colors are true-to-life. The Spyder4 calibrates a variety of wide-gamut and normal-gamut displays. The Spyder4 Express is a cost-effective colorimeter for a single display computer or laptop. iPad and iPhone calibration is also available with the free SpyderGallery app. Spyder4 Pro is ideal for those that want more control over light and color management. Spyder4 Elite provides the tools to manage multiple displays and calibrate them using a full set of gamma and non-gamma tone response curves.
