Open the image in Adobe Camera Raw. Slide the Exposure slider to the right until you have a clear view on all the details in the shadows. In this case I went all the way to +4.

Here I also reduced the blacks (from the default 5 to 0) on the Blacks slider to open up the shadow details.

I also turned down the Clarity to -40. I found this works best with a multiple layer image.

Now, very important... Hold down the shift key. This should change the Open Image button into an Open Object button.

**Click Open Object.
