However, without the direct comparison I don't think I'd be able to see the difference. The new settings are much warmer and whites are clean. I was surprised to see that my monitor had quite a strong 'blue' tinge that made images look quite cold. One useful thing is that after it runs the calibration it shows you a range of 'before and after' images. On a CRT monitor the Spyder has suction cups to stick it to the screen, on a LCD/laptop screen it simply dangles over the top and you align it as required. The calibration/profiling takes about 5 minutes and is very simple. The instructions explain this in more detail. As others have said below, you need to have your monitor set to default to start with otherwise it can throw the calibration off. You will need to know how to change a few monitor settings before you start (such as Brightness, Contrast, etc.). It arrived promptly and was very simple to set up and use. The software in the 'pro' versions is much more complex and there are additional options and configurations. If you are looking for a professional level, you need to buy the more expensive version. The downside is that the calibration is only basic and not Industry-standard. I was shocked at the price of these devices and settled on this 'home user' model as a result. On advice, I decided to properly calibrate my monitor to ensure consistency in the processing of my digital photographs.

However, I got some feedback that my photographs viewed differently on other people's calibrated monitors, and a picture printed for an exhibition came out very differently from what I expected. I had done software calibration on my Mac before but didn't think anything else was really necessary.
