You may be referring to the process of setting your known white and black points to white and black---sometimes called "color by the numbers".

Eddie Tapp calls it the 90% Method of Color Correction. You can download a PDF of it here:

Fred,

I heard the term "nuetralize" a photograph at a TPPA Fall seminar. It seems that you sample the white (with detail) in an image and then adust your red green and blue to the one that has the highest number and then sample black (with detail) and adjust your r g & b to the lowest value. This is to color correct your image. You take your samples from levels. I tried it and it work pretty well....I was wondering if there is an easier way other than using the auto color balance (which I do not trust).

DON'T use auto color adjust. I believe it automatically assumes you have all tones from black to white in your image. If you do, it might work. If you don't have a full range of tones, it will not.

Much better to use what you are calling neutralizing, assuming you have a white point and/or black point with which to work.
