Why calibrate your screen with a Datacolor Spyder ?
 

As the window to your digital photography, your monitor is a tool you need to be able to trust. If your monitor colour isn’t accurate, you won’t see true-to-life colours, highlight and shadow details, not to mention correct skin tones. And if you’re looking at an image that isn’t true, how can you edit it properly, or get your screen to match your prints? You can’t. A Datacolor Spyder will solve all of that in minutes. ith an un-calibrated monitor, the colors in your printed photos won’t match what you see on screen.
