I have done this technique once before but for the life of me, cannot remember how to do it. I have PSP X that I am using and I am trying to turn the picture greyscale and still leave some items in color.........

Can someone explain to me how to do this again???

(I also have PSCS2 but do not have access to it on this computer and need to know how to do it with PSPX)

Thank You all very much in advance!!!
