OK. Here you are:
the source file with the blue marked array:
the first step: faded blured array:
the second steps: faded blured and faded gamma ( lightend for daylight and darkend for a local backward light source in the dark ):
this could be reallize with a slider with directions darken/lighten
The effect will be a photorealistic depth :idea:
:?: If this was programable as an effect it would be great
