I did a real quick job of this.. just to show how I would approach these photos Lightened the shadows some
used Kent Christiansen's Skin Fix Action Paint Soft Skin (found @ atncentral.com
) which employs the Gaussian blur along with the high pass filter which tends to brighten up the effects of the Gblur. You can 'paint' in the softness and use brush opacity to determine how soft a look one wants to achieve. it adds contrast and color adjustments and clone/healing capabilities which I used also.
I only brightened the Iris not the whites of the eyes and added a bit of shine to the lips but left the teeth alone
( I am working with Photoshop Ver 7 so have no lens corrections which I feel these pictures would benefit from)
