My guess is:

he desaturated the image, then used:
image --> adjust ---> posterize
then made an color adjustment layer and filled that with red.

or he cranked up the brightness and contrast of the photo...

*edit* yes he did.

select the part of the image you want to work on, desaturate it, posterize it, crank up the contrast... make a new layer, fill it with that red and put the layermode to 'lighten'. Good luck.

Couldt u be a little more precise.. but its a start.

I think my steps are clear enough...
did you actually open photoshop and try it?
Really, all the steps are in there. Just try it. it won't hurt.
