I would just mention that JPEG compression also introduces artefacts that look very similar to the ones you mention here - did you check the web versions to make sure that nothing extra was introduced?
Hi Steve,
A very fair question, I did try to ensure that the JPG conversion didn't swamp the problem with it's own artifacts, unfortunately it's just as apparent in the original conversion. I'm not sure if it's a case of spill or some other sensor problem given the intensity of the original colour or if it's a function of the post processing. In any case to better illustrate the effect I've made a small 1:1 crop of the original 4096x2734 PX 16bit ProPhoto RGB file saved as LZW TIFF:

Any ideas?
My guess would be that that's the RAW conversion at fault - I'm pretty certain that they're digital artefacts, and by posting the tiff, you've eliminated pretty much every other possibility. What RAW converter did you use (and my apologies if you mentioned it earlier)?
