[LRflex] Re: Digital APO correction in our futures?

Bill -

I'm currently trying out the DX/O version of this sort of thing.   
They have profiles for a number of lenses; in the case of lateral  
chromatic aberration I think they just re-map the pixels to change  
the apparent magnification of individual channels.
