Monitor Calibration

The brightness on your monitor should be adjusted so that you can
just barely see the difference between both halves of the box

Unfortunately, there are no standards whatsoever for monitor
calibration on PCs. Because of that, many people who view my photos
think they are too dark, when reality, all it takes is a brightness
adjustment on their monitors to fix that.
The calibration mechanism described above is the fastest way to get
your brightness level properly calibrated. It is courtesy of Scott Eaton. However,
Vladim Makarov also
has a monitor
adjustment page that might be worthwhile.
