#3 In levels window click on "Set Gray Point" the center eye dropper.

#4 Find something in the photo that looks like its 50% Gray (look in dark shadow area) in most cases their will be a color you can use in the photo.

You can also right mouse click and save this color swatch and use it if you're photo doesn't have

To use it open the swatch along with you're photo put it off to the side of your photo and use it with step #4
