I have Polaroid and I use 600film. During vacation I made some photos. One of them look like that - https://we.tl/tc9D3kc4mQ
Those photos were made at river bank, it wasn't clear sky then and it was around 2 pm. Lower part of photos looks ok, but upper it's way overexposed. I didn't use flash. I also tried to make one with flash but looks the same. In general there is problem sometimes with overexposed photos. I also made 2 days before some photos in a park, and they look amazing - there was much shade.
Have anyone of you had the same problem? What's wrong? Is it camera or maybe I should set special settings for camera before shoting?
Thank you very much for your help.
