NeiL, the post is still available, but just not visible to readers.
As I read the post, you listed the use of plug ins, but did not offer specific steps with illustrations, such that I or any other reader, could duplicate what you did. That does not meet the criteria for GS.
If you wish, I can pm the text of your post to you, so that you can repost it in Finishing School.. It is a fine post, but it does not meet the specific criteria for GS.
[*]Color enhancement in with channel blending in LAB The next two steps will seem very odd at first and understanding how they work in detail requires understanding all four of LAB, overlay blends, layer masks, and the Apply Image command. I suppose that makes them advanced. On the other hand, they are quick to do and could easily be distilled into actions to make them even quicker. I recommend trying this out without thinking about it too much at first. Then you can always learn more about the relevant tools and ideas.
