Photography
Most international brands of print film are available throughout the country, but slide film is only sold in the larger towns. There are good camera shops with spares and repair facilities.
Usually tourists don't encounter problems taking photos, but if you happen to be near a military checkpoint, it is better to ask the soldiers first. People generally don't mind being photographed and many are happy to pose for you, but it is a matter of courtesy to ask first, especially if you are trying to take a snap that includes Muslim women.
