Thanks for commenting. Always interesting to get some frank appraisal.
The RAW file was underexposed across the frame. Here it is as shot with no corrections.
I don't think the centre was more underexposed in the RAW file and I didn't apply any local corrections to the centre (just a little vignetting in the corners to accentuate the centre). I guess increasing the exposure might have introduced some artefacts but I'm not seeing anything really obvious. The cloud was patchy - it's not that. There was some horrible purple fringing affecting the leaves in the canopy - maybe that is what you are seeing as artefacts?
