This is the perfect scenario on why you need to calibrate your LCD monitor: Your photos or graphic projects on your monitor, look nothing like the way they were in your scene or your printout.
What is monitor calibration? Basically, it's a way of correcting your computer screen's color so that what you see is actually how things are supposed to look. Monitor calibration is one part of a color-managed work flow, but it's the easiest and most important step to take, because it's how you, the user and editor of your files, see your images.
