I'll give you some breifly explained tips for the image above:

Increase the contrast using the levels-adjustment (cntrl+L)

Duplicate the layer (cntrl+J)

Add a pretty heavy gaussian blur to the new layer (Filters> Blur> Gaussian blur)

Change the blurred layers blending-mode to "soft light"

Adjust the blurry layers opacity to your "hearts contents"

Flatten the image, and pick the dodge-tool.

In the tool-options-bar choose theese settings: Midtones, Exposure:50

Now paint with a soft big brush over the parts where you want lighter tones (the faces for example).

Now pick the burn-tool. Use the same settings as for the dodge tool.

Paint with a big, soft brush over the parts that you want to darken. (the backround for example).

And now you should have a pretty nice looking picture. Maybe it doesnt work out good the first try, but try agian, and you'll see that for every time you try it, you get more control. Well... hope I helped, if not then just post, and I'll try again !

Duplicate the layer. Do a gaussian blur on the on the duplicate layer. Go to your history palette and click in the box to the left of the current history state (gaussian blur) Then click the name of the history state just below gaussian blur which should be duplicate layer. Select history brush. Experiment with different opacity settings for the history brush. Start with 30% opacity and see whether that is enough. Blur the skin pixels avoiding areas like the eyes, mouth,hair and edges of form where you want the image to be in sharper focus. Use the history brush until you have achieved the desired level of blurring. Merge the blurred layer into the original layer.( Layer, Merge Visible) Duplicate this layer. Set duplicate layers blending mode to softlight. Mask out areas where you don't want the softlight effect and experiment with different opacity settings for this layer.

Dodge/Burn Tool

Simply put, the dodge tool lightens the pixels you paint, and the burn tool darkens the pixels you paint. It’s not entirely different from using Levels or Curves. The difference is that you are not applying the changes to the entire image; you’re applying them only to the places you paint with the brushes. Think of it as a way of selectively adjusting the brightness or darkness of your image.

You can use these tools to improve your images in several different ways:

   1. To improve the exposure of your photo and bring out detail
   2. To direct your viewers attention through creative use of highlights and shadows
   3. To create impact by adding dramatic highlights and shadows

A couple of points before I get to some examples:

Range: The range determines which pixels will be affected, and is probably the most important and most often neglected setting. Muy importante.
		

    * Choosing “Highlights” will affect the lighter areas
    * Choosing “Midtones” will affect the middle tones
    * Choosing “Shadows” will affect the darker areas

As a rule of thumb, you will most often use the “highlights” setting for the dodge tool, and the “shadows” setting with the burn tool.

Exposure: In most applications, the key to effective dodging and burning is subtlety. If you create the effect you’re after without allowing the viewer to detect the changes, the image will have far more impact. For this reason, I suggest setting your exposure to only 3-5% and use repeated sweeping movements over the area you are trying to affect. It makes the changes far more gradual and harder to detect; it also requires a little patience. It’s slow, but it works. I promise. Put on some music or something to help pass the time.
	*As a side note, I tend to also select the ‘airbrush’ option (that little thingy right beside exposure in this picture). It seems to give a little more natural result. No idea why. But really, does it matter why? I didn’t think so. If it does matter to you... you could look it up. Then you could tell me.
