I was in domestic trip in hamedan,iran and i was taking photos of nature and my wife. i did not see anything at moment because i was looking the nature and did not know what captured in my photo. when i was reviewing the photos at home i found a photo with this object. i just see a point in my cell phone and when i zoomed the picture i saw something in disk shape no similarity with birds, airplanes or other objects. as i wrote above, i did not notice that at the moment i found it in my photos, in one photo. it was a thin disk shape with something in white under the object. after i found the object in one of my photos i was feeling happiness and a little bit wondering because i am researching and thinking about foreign objects which sited in earth and i believe about other intelligence life out of our solar system. i am a ufo researcher but never see something like that before. i remember where exactly took the photo but i actually taking picture by using my cell phone samsung a7 from the natures and did not notice the object at the time i was there.
