Pantone's Huey monitor calibration device (see above) can sense and adjust for the changing quality of ambient light, but whether you use one of these devices or not, you need to be aware of the effect of ambient light on, well, everything you look at.

The presence of strong lighting or colours close to your monitor - room lighting, even clothing, can affect the appearance of on¬screen colours. And a print viewed under artificial room lighting will look very different if you take it outside into the daylight. Before you start adjusting monitor and printer settings, take a second to consider whether the ambient lighting conditions are the cause of your problems and choose a neutral desktop colour (white, black, or grey) for viewing photos. If you can't bear to be without your rainbow desktop, use your photo editor's full screen or sideshow mode.
