A common problem encountered when displaying magnetic data as a color image is that small amplitude variations, which may have geologic significance, might be lost due to the large dynamic range of the whole data set. The human eye is capable of distinguishing only a limited range of variations within the color spectrum. Enhancement of the low-amplitude features is usually achieved through some type of image transform. By far the simplest approach to this problem is modification of the input limits of the datA—i.e., the operator selects a subset of the full dynamic range. To investigate the full complexity of...
