FAKE HDR

I am trying to create a fake HDR script based on this gimp routine

http://registry.gimp.org/node/11776

and am stuck here:



deblock0519 0_906_____ = SFileIn("//Fileserv/files/jig/jig0519/avisynth/deblock/deblock0519_0-906@@@@@@. tif",
"Auto", 0, 0, "v1.1", "0", "");
levels0519 0_906_____ = SFileIn("//Fileserv/files/jig/jig0519/avisynth/levels/levels0519_0-906@@@@@@.ti f",
"Auto", 0, 0, "v1.1", "0", "");
Saturation1 = Saturation(levels0519 0_906_____, 0);
Invert1 = Invert(Saturation1, "rgba");
Blur1 = Blur(Invert1, 90, xPixels/GetDefaultAspect(), 0, "gauss",
xFilter, "rgba");
MultiLayer1 = MultiLayer("v4.0", "L1", 0, Blur1, 0, "L2", 1,
0, "Outside", 1, 0, 0, "rgba", deblock0519 0_906_____, 2,
"L1", 0.2, 0, "IDiv", 1, 0, 0, "rgba", 100, 1);


// User Interface settings

SetKey(
"nodeView.Blur1.t", "0",
"nodeView.Blur1.x", "333",
"nodeView.Blur1.y", "192.5",
"nodeView.Invert1.t", "0",

"nodeView.levels0519 0_906_____.tnTime", "1",
"nodeView.levels0519 0_906_____.tnVisible", "1",
"nodeView.levels0519 0_906_____.x", "363.75",
"nodeView.levels0519 0_906_____.y", "390"
);
can someone point me in the right direction to get this HDR look?
