Making the most of Highlights

If your image has some subtle highlights that you want to make really stand out but not blow out you can try this simple method
-Make a merged copy above your retouching layers
-Make a color range selection of the highlight areas-turn off localized clusters
-Make a new adjustment layer>solid color set the RGB setting to R=252 G=252 B=252 so that this highlight area will not be lost on printing
-Highlight your mask
-Set your history to the current state
-Fill the Mask with black, CTRL+Backspace
Paint with the history brush to reveal only the areas that you want to. The history brush will not allow you to reveal any parts of the image that were not part of the original selection area.
-ALT+click on the mask to see the mask in your work space. You can blur the mask to create a softer edge to the new highlight
-lessen the layer opacity if you find that the highlight is too aggressive
