I still haven't gotten the hang of the whole "layers" thing in Photoshop.  It seems so unnecessarily complicated.  I really need to read that book!  This one I used the magic wand again (did I say lasso before?  I meant the wand - sorry) until all the bits of the bandana were selected.  Did a reverse selection, and desaturated using the Photoshop controls.  No outside filters on this one.
