For much of the time that I owned my current PC I had a bad monitor and did not know it. It made pictures far darker than they actually were. As a result I often lightened my pictures too much. When my old monitor finally blew out completely I got a new one, and I could really see the problems with my old pictures. I was able to fix some of the them, but others were lost causes.
Attachced are photos of the reverse of an 1831 quarter in NGC AU-58. The coin has been dipped bright white, but it's still very attractive. The photo on the left of the picture is the coin as it actually looks. The smaller one on the right is the coin after one of my experiments failed to fix an old photo. As you can see the coin now has "color." This provides an example of what a scam artist could do using some simple software, in this case Microsoft Photo Editor.

Monitors are like TVs. They are set with the brightness maxed out at the factory. This is because people want to see a bright screen at the stores, but the stores are already too well lighted. Brightness almost always needs to be turned down on new monitors and TVs.
* the lighting in the room
* the type of lighting used (fluorescent, incandescent, natural, etc)
* the quality of the monitor
* the age of the monitor
* how many magnetic interferences there are near the monitor
* the video card
* the human eye (including all forms and degrees of color blindness)
* the source of the original image and all those factors above that influenced how that image was made
