Good morning, I've re-run all the shots. 1st series with a gate as subject 2nd series a window sash 3rd series a white ceiling to assess vignetting
Some notes: In the first series you can clearly see the AC phenomenon against the sun. In the third series no development has been done except for the one applied by default by DarkTable, if you want I can develop also these images or remove also the generic development done by the software. The shots of the third series are all out of focus. For your convenience at this address I insert the folders containing the jpeg files and 3 .rar files, one for each series of shots.
