learned something new today carl, but it also gave me pause for thought, you see the way you attacked the problem addressed the most visible issue of chromatic aberration (yay im using my new found terminology too!) The fringing as you put it, but thats not actually whats going on here right?
As lightsources of various intensities strike the lens and refract at different angles, the refraction and therefor offset of the color in composition must be a relative amount, not predictable so much as scalable to eachother, that is the greens and the blue and the reds shift along the same direction in different amounts right? It sounds like a better strategy would be to SHIFT all the pink (or maybe even red) values to the point where there is no fringing visible, since all of the color data, not just the edges are off this will give you a more accurate results... Or maybe I'm wrong. It sounds like shots with these problems might be more salvageable then we might credit them for. Just a thought.
