[HeadUp]

i just got ps7 and i read magum's sticky about blending, i have it to the point where Spiers is the only one in the pic (the background is white). Then magum jumped to putting the parachute picture behind it, that is what i can't figure out. How yould i add, say, a blurred background of th beach invasion from SPR?

Also, does anyone know why lense flare and lighting effects (under filter), only work with certain pictures? I am working on a pic with a bunch of soldiers against a busted wall, i want to make the sun shining through, nut i cant do a lense flare-- why?
