Xero has free filtres and that one looks just like the "Porcelain" filtre. I use it all the time. It gives off the glow and leaves a wee bit of bluish tinge to the image.
This one looks like it was given the Porcelain filtre with a deeper intensity.
Just type in "Xero Filtres" (or Filters depending on your location) and it should take you to their site.
