Hi Chaps,
All this technical stuff is incredibly fascinating ... but does anyone actually know how to "easily correct" it?
I would guess not in case like this, since there is a major loss of original colour/contrast information on the affected area. When the fringing area is this large, reducing purple saturation will leave an unnatural black/grey halo, and transforming the image to B&W likewise results in a strange grey halo on the nose.
Ian, it looks like you are using a very small part of an image - do you need to crop it so much for real-life usage, or did you only do that to demonstrate the problem?
I ask because this problem often occurs with stage performances, and the best way around it is ultimately to get closer to your subject or use a longer lens - this won't 'cure' it, but it will make the affected area less significant in relation to the size of your image. Also, try experimenting with this type of high contrast/sillhouette shot until you find the optimum settings/situations for you equipment (for example, dark background light subject or subject completely 'blacked out').
