The background on the one on the left looks like the protrait paper background from Daz. Also, on that image, it reminds me of a tutorial I saw once that explained how to make one part of an image in color and the rest of it kind of black and white. It think it was at Daz also. The image on the right looks to be a spotlight on the face and then postwork to turn the image into a black and white photo. Just my opinions though.
