I'm sure you are right. Now if we could just replicate the neural pathways, we'd have a plugin.

Well I was thinking along those lines by:

I suppose, in theory, one could apply shifts based on putative changes in relative distribution of RGB channel luminance (%) with depth, if such data, however generalized, can be derived or obtained, but like I said, there are so many variables involved that you couldn't expect that it would magically 'auto correct' your footage - at best broad shifts in the 'right' direction, maybe.

Like I said, I was only interested in seeing how these correction methods hold up in varied scenarios. Purely that. I hope it won't be taken that this will lead to something. No preferred file host for me, as long as its safe.
