The effect you are after can be achieved:

  • Duplicate the image layer containing the forrest image
  • make the new layer black and white
  • invert the colors (ctrl/cmd+i)
  • on the black and white image: select all (ctrl or cmd + a)
  • copy the selected

  • click the original image

  • create an image mask
  • go into channels
  • select mask channel
  • paste

  • hide the duplicated black and white image (that you used for the mask)

this should create a mask that makes the lighter areas more transparent.

this is how it looks in photoshop when done
