Imagine you are a popular content creator on PixelFed, many followers, but many stalkers also. You don’t want people to know where you live. One day you post a picture of the sun out of your window. Exact time is attached in metadata. Assuming GPS metadata is stripped, can someone, using inclination of the sun to the horizon, Nautical Almanac and some math calculate your latitude and/or longitude, and to what precision? Assuming also meteorological data archives on cloudiness, etc.
It all depends on the land in the picture.
If there were only sky and sun, nobody knows direction or height or place.
