No, Shadow/Highlight won’t work as an adjustment layer, but I did stumble on a near solution. For some reason, you have to do it early, if not immediately, in your picture editing sequence:

-Apply shadow/highlight to your liking and mark the result as the history state on the history palette. (Put the little eyeball in the box next to it.)

-Click on the previous history state, which likely will be the one labeled "open." (But don’t mark it as a history state, you’re just backing up in sequence and making your s/h adjustment temporarily disappear. Also, this is NOT the same as "undo" or Ctrl-Z!)

-Create a new layer and select that new layer.

-Select the history brush tool, making sure to click on the "select all layers" box (I think that’s what it’s called–I don’t have the program working on this computer), and brush the "s/h history" onto the new blank layer wherever you like.

Advantages: you can apply the history brush in modes (lighten, darken, etc.) in different parts of the picture, and in various percentages. This method also allows you to put your further retouching steps on the same new layer. The original file remains untouched on the background. Plus, I think this makes the final PSD file size a little smaller than it would be if the background were simply duplicated.

Drawbacks: For some reason this sequence just won’t work if I don’t do it right away. The history brush simply won’t function. I’d be happy if anyone can tell me why that is. MB

Now that have Photoshop in front of me, I can correct myself.

The little icon in the square of the history palette is not an eyeball but the little history brush symbol.

Right Michael, so you can take a snapshot at any point, and use that as your history source. That may be why sometimes "it works" and sometimes it doesn’t.

Of course! Make a snapshot! I don’t know why, but I always forget about that option. Thanks.

Also…shadow/highlight does work on a duplicate layer…problem with history states is that you can’t go back and edit them 2 weeks, 2 months or 2 years later. And after 4 or 5 snapshots you totally tank the RAM on the machine.

You can even apply other corrections first, then stamp (Control+ALT+Shift+E) duplicate the stamp layer and apply Shadow/Highlight to duped layer last, right before sharpening.

Try the Luminosity channel trick on a copy of the L channel pasted as a layer in the file. Run shadow/highlight on the copied L channel layer…set the layer’s blending mode to luminosity…WOW
