Techniques for differentially enhancing selected areas within a digital image are disclosed. In certain embodiments, one or more attributes of a selected pixel or a group of pixels is determined. Examples of such attributes include color properties, grayscale properties, and/or multi-pixel properties, such as texture. In certain embodiments, the attribute may be used in conjunction with the properties of a modification tool, such as a brush, to selectively modify pixels having the attribute value or a similar attribute value.
