Hi DD team
I learned that if the camera is set to automatic the ISO values vary.
I still don’t understand why that on very sunny summer days, the ISO values vary between 100 and 1600.
The effect if pictures are not normalized using Lightroom:
Multiple stripes of blurred, unstructured areas as pictures are overexposed.
Result after pictures have been corrected with Lightroom before processed with DD:
Blurred stripes are much smaller. Much more structured areas.
