the instructions on that site DO NOT work on the adobe ps cs3
am still searching around for relevant site .Have been directed to a site called fotofushion ,so am in process of nutting it out .There would be a way around it ,has to do with just blending the 2 together.Any help most appreciated ...will let you know how i get on.
Sorry fi ,as this isnt really regarding your image , but as to do with technique thought would just let you know that ,following those steps via the link you gave is from what i get from another photography forum site ,its only for ps1 ,again thats just from others that have also tried.
no luck
