Color calibration is an important, though often overlooked, field. Many people buy their display hardware, plug it in, and just assume that it looks correct. Some people go ahead and make a few changes to their display after installing it, configuring whatever features they see as being inaccurate. This sort of subjective analysis is a step in the right direction but it can only take users so far; at some point a more objective and scientific method is needed. For people who see accurate color as being very important, the type of testing needed is best seen in a hardware-based, external device. One such device is the Spyder2 calibration tool from Datacolor. This device plugs into a computer's USB port and mounts on the display. From this point it is able to analyze many different aspects of the image so that the monitor can be properly configured for an accurate picture..
