Open up your picture in Photofiltre. Click the selection tool on the Ellipse setting.
Make a selection around their faces like mine:
Now go to Filter >> Stylize >> Progressive Contour and set your settings like mine and click ok. Do this twice.
Now right click on the selection and select Invert Selection and your picture should look like mine now:
Now click the gradient tool and set the style to Duotone, Direction to whatever you want it doesn’t matter, and the both the colors to black at 70%. Do this step twice.
Now you may have little parts where it isn’t quite perfect like mine. Well just take the Blur tool (R) and have it on Precise and opacity=100 and blur it away.
After you blur those away just add effects. I clicked twice and once.
