Bruce... ...and interested Others:
The reference SkinColors image previously posted and its use with the Mask Tool - Color Range feature and the Saturation transform in HSV mode is described here: "Vibrance vs. Saturation and PWP's Saturation transform": http://www.dl-c.com/board/viewtopic.php?f=4&t=594
Used in the manner described, it can provide an uniform saturation change in the HSV-H,S plane [color hexagon or color wheel] while at the same time protecting SkinColors and High saturations... ...for example: ...However... for a quick straight forward approach, the Color Correct transform with the purposed preset can also provide vibrance [protect SkinColors and High saturations] inspite of its lack of uniformity. Sometimes its lack is a preference. For example, if the Preview image's sky is too Blue [HSV-H = 66.7%], its arrow can be shortened as well as the adjoining Aqua [HSV-H = 58.3%] and Purple [HSV-H = 75%] hue arrows... ...and more SkinColor 'blocking' control points can be readily added... ...all are changes that can 'customize' the HSV-H,S color hexagon to a preference for a specific image... ...for comparison with the Saturation transform illustration, here is an illustration of the suggested vibrance ColorCorrect preset: Again... ...for most photo realistic images, the lack of an uniformly applied saturation change is not readily apparant and provisions for 'artistic' control for specific colors are available.

Ask if there are questions... ...perhaps some thought should be given to understanding the question as well as than the answer... ;-)
