Question: My friend and I are thinking of going to Tehran and taking some video footage- only indoors. Our footage would have nothing to do with protests, or government, etc. How careful do we need to be with a small camera?

Answer: Of course you can bring a normal ordinary-size camera to Iran, but if it is professional, then you have to get written permission beforehand which takes about 10 working days.
You should take care not to take films of the sensitive areas in Iran such as the military bases, governmental offices, airfields, airports and other sensitive areas where photography is forbidden. Most of the holy shrines in Iran do not allow photography. So it is better to look for sign or ask the staff before taking photos. Ask for permission before taking photos of other people.
