Without the processing (Scrap) I see no ring around the sun - it's better without one. Perhaps you've used the rebuilding/recovery in Photoshop to strong?
Thankyou. Interesting. I have had a look back through my processing and I cannot find where the error comes from. Usually this kind of artefact results from camera/colour profiles within Lightroom. I have not used recovery. It's a bit of a headache now...I will have to return to this at a later date.
it color channel clipping...Its unavoidable if you have high levels of saturation shooting into the sun. Best thing you can do is use exposure averaging to soften it. Or avoid the oversaturation in this particular case
