Michael Mozina,
Since you are an expert on the running difference process, perhaps you can answer the question implicit in GeeMack's post
Why does the apparent height of your "mountain ranges" depend on the selection of source images for the RD process?
First answer:
And the obvious rebuttal:
This has nothing to do with actually measurig the heights.
This is the fact that by changing the amount of time between the source images, the apparent height of the mountains changes.
In other words
- Your light sources remain the same regardless of how the images are processed. They may move. They may brighten or darken.
- Your "mountains" remain the same regardless of how the images are processed. They may be made of some magical material that moves along your crust or changes height during the.
- Create 2 RD movies. The apparent heights change.
But your light sources have not changed between the movies. Your "mountains" not changed between the movies. Thus their apparent height should not change between the movies.
So here is the question a bit clearer:

Why does the apparent height of your "mountain ranges" depend on the timing of source images for the RD process when the light sources and mountains in the images are the same?
