Others call it sensor blooming. But if you check the
wikipedia article on purple fringing you will see that the definition is quite generic and the sample provided is not one where purple surrounds a bright spot - it is closer to what wlachan posted.
Happy to call it whatever - sensor blooming sounds ok to me. It's the removal that's the hard thing to do
If my first attempt at attaching a picture works
, you'll see that "purple blooming" applies in 2 ways, where if I remove the unwanted purple edges around the icing, the agapanthus petals on the left are also affected (not that it bothers me in this happy-snappy) ... fyi, the lighting is indirect daylight coming from the south (Australian orientation), so not really backlit.
