Visibility I / V
It was difficult to get the actual phenomenon for the cell. It was a very mild 22r, but more attention was drawn live to the inside of the perimeter. Radial areas were especially visible at the bottom. The vision was very reminiscent of a giant eye and the radial lines of its iris. I tried with Snapseed to get the lines out better, but the visual observation does now beat the images 6-0.
Edit. I added one Hdr-scape-treated image with Snapseed. In it, the rays go down to the perimeter. Corresponds to more visual perception.
