Testing Nik Software's Viveza
This plug-in isintended for people making color, tone, or contrast adjustments to selected areas of an image. For example, maybe you want to brighten a person's face, or increase the contrast in a particular texture. The trouble with performing these types of operations in Photoshop is that it can be difficult to cut a mask that creates a smooth transition into surrounding tones. I will post the results of my experiences soon.
