Ok in case you didnt know, I do use photoshop to help bring what I see out. I try not adding anything. I just usually burn and dodge the image to show what I see. I lighten the lighter areas and darken the darker areas. I have no problem seeing these faces everywhere...but most others would. I post most of my originals in my scraps page in case you want to see what I do to the images. And as you can see, you can see the images in the original shot still....just not as defined.
