In line with shAF's white and black point setting suggestion, there is an
excellent site at http://www.aim-dtp.net/aim/index.htm, very professional
but understandable and lots of how-to-do-its.
There is a monitor calibration section there, and a good walk-through of the
white and black point settings at

| Each device has an associated "black" and "white", both of which
| are generally similar across all devices (forget for now the color of
| white, eg warm vs cold). Between black and white however, is how a
| device responds to the data (eg, monitor), or its stimulation by light
| (eg, camera+film). This response is generally refered to as the
| device's "gamma".
