H,
I think this might be something half new (at least in this arena)
I am guessing (but dont know) they are using typical known and determined PSFs (Point Spread Functions) of lens aberrations to closely approximate the actual PSF of your particular lens and then run their algorithm to refine that PSF and then deconvolve.
Plus apply corrections to other sorts of aberrations and even possibly using different PSFs across the image to more accurately correct it.
One day some bright cookie will create something that can do this for all your lenses by imaging test targets and then accurately analysing properly and correcting. Meaning that an imperfect lens might be capable of taking a near perfect picture (after processing).
Quite possibly in the camera !
Which may in fact mean that lenses could be made much more cheaply as they dont have to be perfect, just be able to be analysed for their errors and then corrected.
Of course that might be expecting more form the technology than is currently possible, but I think in theory its possible.
BTW - While I can see the improvement in detail and contrast between the 2 versions of your image that the software has provided, I have to say that I actually prefer the first one !
It has that wonderful hand painted and aged toned look about it.
The second one just looks like a sharp landscape photo rather than a scene with mood and personality !
