[quote='[1ponders]'] Even using utilities such as Adobe Gamma Adjust, many of the programs rely on visual perception of the screen, which will change depending ambient light conditions, age of the monitor, monitor temperature etc. I've considered the hardware option, however of some of the more reliable systems can be quite expense, ridiculously so at times.

Yes, Adobe Gamma is not good on LCD monitors. You also need to update calibration regularly and always work under the same lighting conditions. Some of the pros calibrate monitors daily, but monthly is probably OK for normal people. Spyder is probably the cheapest hardware option. I got one in the US for $US200, but the Aussie version costs more than twice as much--I can't think why, it's the same product. Still, even $500 is not a great expense in terms of the total cost of scope, mount, imaging devices, laptop, etc.
