After a day of dining and wine tasting at numerous winelands and the last - Matawhero Wineland, we headed back to the car. My family was already in the car and I decided to take a picture with my iPhone 6 with everyone inside the car.I felt like deleting it immediately, but kept it and just before entering the car I took another picture of a crowd of young adults playing cricket on the opposite field (with no "spot" on the lens).As I was scrolling through my photos, I came across a dark spot in the background and thought it might have been something on the lens but since the second picture of the young adults playing cricket did not contain any spots on the lens, I investigated further by editing and zooming into the photo.The dark object clearly has a ufo shape. It was a little blurry in the background because of possible movement and/or lack of focus.
