Je me doute que ça n'est pas fait pour prendre des photos, et je profite en général juste du moment,

mais je me demande si il est possible de ne pas avoir de cercle lorsqu'on s'y prend avec un téléphone

It was "growing" on the walls of an old barn behind abandoned petrol barrels, after a closer look it seems like its in a lot of crevices in the barn.

Might be something like salt as it is sort of solid to the touch and some fell off when I took the barrels away, will answer questions if necessary thank you for the help 🙏 (sorry in advance if it turns out not being mold)
