Contrast enhance in dark area

This an adaptation from

http://www.gimpguru.org/Tutorials/ContrastMask/

The original methode (for photo)

1. duplicate layer
2. duplicate layer -> B&W
3. B&W -> negative
4. negative -> Mode = Overlay
5. Overlay -> Gaussian Blur 10-30

An AviSynth adaptation

b = a. GrayScale().Levels(0,1,255,255,0)Blur(0.2,0.2)
