Monitor Calibration
When you view photographs on a computer it’s best to have your monitor’s brightness and contrast adjusted correctly. You can use the image in the panel to help you set your monitor up. This is a simple, quick fix to a complex issue, but it produces good results.
Adjust your monitor’s brightness and contrast so that you can see every level of grey:
Contrast
Typically the contrast setting on the monitor should be at maximum, or very high. The contrast control adjusts how much difference there is between the darkest shade and the lightest shade on the monitor. You are aiming to get pure black and pure white. It’s not normally possible to get real black, due to the inherent properties of the monitor. If you think you have black, hold an object you know is jet black next to the monitor - you may be suprised!
Brightness
The brightness setting should then be adjusted so that the black is black and the white is white, and there is a noticable difference in shade between all adjacent squares. However, the difference between the 95% and 100% shades is normally smaller than between the 0% and 5% shades.
Once this is done, your monitor’s more or less set so you can see websites and photographs as they’re intended. Remember that as your room’s light level changes through the day, and your monitor warms up (even an LCD), your monitor’s settings are no longer at their optimum and need changing. You could also follow your graphics card’s calibration wizard, if there is one.
