Neverfly,
In the very first image linked in the thread (a tiny image, no time at all
to download) is a left-to-right light streak which tapers at both ends,
surrounded by dark areas. The dark area below the light streak is very
narrow. I think the light streak is what is being discussed. The only
thing about it that looks unusual is the linearity of the dark area below
the streak, like the shadow from a cliff. Here's the link:

I get a better view if I increase the gamma of that image. I just applied
a gamma correction of 2.2.
Jay,
Now it's my turn to ask for help. What image or images are you
suggesting may have been altered?
What platform does the 3D contour analysis software run on?
