Although the Iranians themselves enjoy taking photo of their families, they are not yet used to the sophisticated photographic equipment that foreign tourists like to deploy, and May well regard some of it as highly suspicious, especially zoom lenses. Groups of tourists descending from a bus with their cameras at the ready and shooting off in all directions make policeman particularly nervous. Be careful where you point your camera and avoid taking pictures of policeman and soldiers. It is strongly recommended that you not take pictures in or around airports, military installations of any kind, barracks, frontiers and any other sensitive area. If in doubt, ask your guide(policemen have been known to forbid pictures being taken in the street, especially in small towns). When taking photos of people. Particularly of woman, ask their permission beforehand.
Photography is permitted at most historic sites and even in some museums (without flash) but not around certain holy shrines such as Mashhad and Qom. In imamzadeh (mausoleums of the descendants of Imams) check first with a guardian to make sure that photos are allowed.
