That seems like a simple effect. Here are a couple of ways you can go about creating it:
1. Duplicate the original photograph.
2. On the duplicated layer, change the brightness/contrast drastically. (for example: increase the contrast by + 35)
3. Apply a gaussian blur of 5 or so on the duplicated layer.
4. Reduce the opacity of the duplicated layer to around 50%.
Obviously there are various other ways of reproducing these sort of effects, but if you have a specific one in mind, please ask.
