Elements has the fill light tool to brighten shadows, and this works well to bring out features lost in darkness. However if the photo is very badly exposed and there's no detail captured in the shadow, all you'll get is noise. Mostly though you adjust the shadow/highlight tool to bring in detail in the shadow, but not so much that the features look noisy or overbright. Photoshop's shadow/highlight tool is similar to Elements Fill light, but naturally it works a tad better. Likewise you make the picture brighter, sharper, bluer sky, more contrast, richer colour - you can even give yourself a darker/lighter tan and whiter teeth [or copy across the head from someone else if you want].
