Sorry for my noob question... it should be a very simple thing to do, but I can't

How to make a normal photo look like that? It's not simply B&W...

Thank you!!

Yes it is.Is Black and white, the question is: How much black and how much white and how to get a nice picture like that.
Desaturate, play with levels dialog (for more power use curves instead)
