Just duplicate the image, desaturate it, crank up the contrast/brightness, and see if you like what you're getting.

 

Easy...

That's exactly what I did, Claudio, and got some good results.

 

In Photoshop, I loaded the image, copied it to a new layer, Image -> Adjust -> Desaturate, then selected Image -> Adjust -> Curves. PS comes with a bunch of presets. I selected the preset Increase Contrast and then dragged the handles on the curve so that the middle most 2 handles were close together. This tends to 'squeeze' the gray (or mid-range of values) out, leaving a very contrasty image.

 

Here's my effort:

Nice...V-Ray?

No, Mental Ray. But I'll take that as a compliment.
