More like "How to make a coke bottle behave like a pepsi bottle"

Such correction software is really appropriate for making crappy lenses 
into less crappy lenses. The problem with turning a crappy lens into a 
great lens is that by the time the light has hit the film or sensor 
plane, there is also a ton of light that has gone off in other 
directions ... that is what should be in the image has been spread out 
in a volume between the lens and the sensor. Now if you could properly 
image that *volume* you actually could reconstruct an entirely 
corrected image (via 3D deconvolution). Of course its alot cheaper to 
get the lastest APO Asph in the first place.... *

* that said, image enhancement software can improve resolution etc to 
some extent.
