Remember to respect others privacy and especially home life. Do not fly above other peoples homes in a disturbing manner or publish photos of people without their consent.
Crimelaw prohibits the photographing or surveilance of people in private areas such as homes. You don't need a permission from people if you are filming in a public place like a marketplace.
Filming is allowed in streets, roads, forests, market squares or other such public places, but publishing pictures from these areas without consent of the filmed people where a single individual can be recognised is not allowed.
