I was taking photos for an assignment for school on february 27th, 2020. i did not notice anything back then until a few weeks ago in april i was editing the photos for another assignment and i saw something peculiar in the image so i started to play with dehaze, textures and contrasts, etc to enhance it and i saw the shape more clear. the interesting thing is there are 3 planes around the object so is easy to compare and see the difference in shapes. i took more than one photo at that moment but just one it shows the object. i have a raw file if needed. thank you.
