Monitor Calibration

Monitors are often calibrated differently and so what may look like a wonderful contrasty image on one screen may look utterly dull and dreary or just plain dark with no detail. If you are having problems viewing the images on this site the by following the guide below, you should be able to get a fairly accurate likeness.
1. Colour depth:
The image to the right should contain only smooth changes in colour. It should not be dotty (due to dithering), or contain sudden steps. If this is not the case, you will need to set your computer to a "High colour", "millions of colours" or "24 bit colour" mode. You may need to reduce the resolution to achieve this. Then close and restart your browser and have another look.
2. Brightness and Contrast:
Adjust the brightness and contrast controls on your monitor so that you can see eleven discrete squares of different greyness in this image.
3. Gamma:
Finally, there's the question of gamma. On my monitor, the inner and outer square in this image appear to be about the same shade of grey. If you can adjust the gamma on your display (which is possible on many Macintoshes and Unix machines), try to minimise the difference between the inner and outer squares.
