I wish we had Automator on Window$ (or that my employer and everybody goes Mac, but as I work in an industrial context, it's less than improbable). I did mine with Python + Exiftool + DNG Converter. Requires quite lots of extra to be installed, though: - Python - Perl (needed by perl) - Exiftool - DNG Converter > > My personal experience with a few lenses is that the AC does not > > significantly change with the aperture. > > I don't find that to be true. CA differences at wide and small > aperture are easily seen with most lenses. Again, I might be able to interpolate from a finite set of apertures. What I have in mind is some kind of "learning system" such as: - Tweak the CA correction manually in real images, in Camera Raw. - Give the tool the modified DNG, and it stores the CA values as "reference" values into the database (with lens id, F, aperture, distance range) - The more points you store for the same lens, the more accurate the automatic CA settings become (hopefully). - If you see that the auto CA chosen for one of the images is wrong, refine it, and feed the image to the tool again. It should get better over time. I can't see why these CA values would follow a law that can't be modeled with a simple bilinear approximation. I may be wrong, in which case more sample points would be needed. > Lenses that focus via whole-lens displacement show little CA shift. > Rear element and front element focusing lenses see a modest amount of > shifting, and lenses with both internal zooming and internal focusing > show the most. Those fixed size lenses are handy, of course there's a price for this. Patrice
