Aerial photographs have been taken of tulip fields in the Netherlands.
Similar ethics surround the concept of private vs public land. My assumption is that crops and farm land are private land, although, the sky less so private giving the opportunity to fly over and take photographs.
This debate appears to be quite silly though, I mean these tulips look beautiful and the photos display that. So why is it seen as OK to shoot these but for frowned upon for urban exploration photographs? After all it’s just different people’s views on what an amazing photograph is, and the subtle difference that one is trespassing and the other is flying over fields.
